10 Tips For Students To Write An Excellent Essay

10 Tips For Students To Write An Excellent Essay You should be able to provide the thesis statement in one or two sentences for a fairly short paper (about 1-8 pages). It is usually best stated at the end of your introduction section . The introductory paragraph should briefly orient the reader to the topic and provide a conceptual map of the rest of the paper. Although writing an essay is daunting for many people, it can be pretty straight-forward. Duke requires one supplemental short answer and gives students the opportunity to respond to two optional prompts. The third essay prompt of the Common Application asks you to open up about a time when your opinion was unpopular. How can you write a powerful essay without polarizing readers who disagree with you?

Well, you shouldn’t write about a community-service initiative just because you think it’s what admissions wants to hear. Some essays about volunteer efforts inevitably come off as inauthentic . Harvard University is one of the most competitive schools in the country. Every year admissions officers are bombarded with applications from eager students looking to make the cut. Thus, Harvard has a supplement to give students an opportunity to distinguish themselves from the competition. It should be an appropriate guide for writing at the middle school, high school, and lower college levels. The typical assignment I have in mind will be an argumentative essay, in which you argue for something, even if just an interpretation of someone an author’s work. Can you write about volunteering in your college admissions essay? A good way to tie all the points together throughout the body section is to have them all clearly state how they support the thesis statement. That way it is obvious that all of your paragraphs tie together. Note that the first sentence of the paragraph may satisfy both goals. That is, you may have a topic sentence that also serves to transition well. Another option is to have a transition sentence first and then a separate topic sentence following it. That is, you have something you want to communicate or argue for and here is your chance to explain it in detail, support it, and defend it. Make sure your thesis statement is clear, specific, declarative, and on-topic.

For example, are you able to show how much damage is caused by using sleep medication and the statistics and tests that prove it? If so, you can start building your case from there. Therefore try as much as possible to remain meticulous in your review. Remember, you do not have to be verbose to make the essay clear and interesting. If what you are writing about is a unique experience, try to use ordinary events to describe it. This tends to be more informal and will contain narrative aspects as well as some entertainment value. Remember, this is a skill that you will draw from in future, whether you take on writing as a career or pursue a different professional route. Therefore, practice the art of getting your objectives right from the beginning before embarking on the project. A personal essay should be structured in such a way that it provides an unbroken reviewing experience. It should be written in story form covering an incident or incidents that have occurred. These could be either situations which you have personally experienced or you have some personal knowledge about. What type of evidence is required in a persuasive essay? It needs to be specific, with solid sources quoted as opposed to generic statements. Critical has its roots from the Greek word 'kritikus' which means 'to discern'. This is the essay that challenges the concepts behind an issue. Ensure that your thesis statement is not too long.

Why I cannot send you PDFs of my books

In recent days, Ive received an  increasing number of emails  from people  in various countries requesting PDF  versions  of my books, often for free. Their reasons range from the perfectly valid to the somewhat  questionable to the frankly clueless. Unfortunately,  I cannot accommodate these requests, no matter how compelling the reasons. Let me explain. I am not denying these requests for the sake of being difficult, or stingy, or cold-hearted. Rather, the reasons have to do with the logistics and economics of self-publishing in the digital age. First, my SAT grammar book (albeit the original version) is available for  Kindle download  through Amazon. Im not sure what the international restrictions are, if any, but in theory it should be downloadable from just about anywhere. As for  The Critical Reader,  I  am legally prohibited from distributing it  electronically. The book contains passages taken from a number of  copyrighted sources, and in order to include them, I had to obtain  legal permission  from various rights holders   a process that  involved dozens of emails, several thousand dollars, and, in several cases, waiting periods upwards of six months. Most of the contracts granting me the reprint rights to the passages  stipulate that I may only distribute  a print version of the book. Sending out PDFs of the book would be a breach of contract on my end, and  could result in my being sued for  thousands or even millions of dollars. In addition, please consider this: my books represent months and in some cases years of work.  They are the result of thousands literally, thousands of hours of unpaid work. The second I put my   in someone elses hands I lose control over its distribution. It takes half a second to hit the forward button and send a PDF to someone else, who in turn sends it to another couple of people, who all send it to another couple of people, on of whom  posts the entire 380-page file  on College Confidential for free download as Ive seen happen with other books. Aside from the lost royalties, when (if)  I discover that my books have been distributed on the Internet and do nothing, I am at risking for losing my copyright that is, I could potentially lose the rights to my own work, which I spent all of those years producing. In order to protect it, I have no choice but to take very expensive legal action. I  am in the process of investigating ebook options. If I am able to find a relatively straightforward means of having a secure electronic version of  The Critical Reader created, then it may be worthwhile for me to go back to the various publishers I am beholden to and request electronic rights. But that will be a longterm process.  In the meantime, there are  risks I simply cant afford to take.

Soon following Locke’s birth, the family moved to the market town of Pensford, which was located about seven miles south of Bristol, where he grew up in a rural Tudor house in Bellution. At the age of fifteen, Locke was sent to the prestigious Westminster School in London under the sponsorship of Alexander Popham, who was a Member of Parliament and his father’s former commander. After his competition of Westminster School, he was admitted to Christ Church, Oxford. Although a Locke was a b right and capable student, he became irritated by the undergraduate curriculum of the time. After finding works of modern philosophers, such as Rene Descartes, in which he found to be far more interesting than the material that was being taught at the university, he began to start focusing on philosophy. In 1656, Locke was awarded a bachelor’s degree in medicine, and two years later in 1658 he was awarded his master’s degree. Having studied medicine during his time at Oxford, Locke worked with noted scientists and thinkers such as Robert Boyle, Thomas Willis, Robert Hooke, and Richard Lower.

Explaining A Concept Essay Example For Students

Explaining A Concept Essay BIPOLAR DISORDER1Bipolar Disorder, often called Manic Depression, is a medical condition thatinvolves severe mood swings in an individual. It is a lifetime condition that needs to betreated to keep it in remission (APA). It is not just a mental illness, but a medical diseaseinvolving the brain. 2The disease progresses as the years pass and the frequency of mood changingepisodes becomes more frequent (MHN). Bipolar Disorder involves depressive and manicphases. With the symptoms presented, clinicians often misdiagnose patients asschizophrenics (Shalala). 3Bipolar affects an individuals thoughts, feelings, health, behavior and ability tofunction. The disease is not a result of a weak personality, as many people believe. Instead, it is a medical condition where there is an instability in the transmission of nerveimpulses of the brain (neurotransmitters) that signal appropriate moods (NDMDA). Thebipolar patient responds with inappropriate mood swings independent of what is going onaround them (APA). Bipolar compromises the judgment of those that suffer from it. Some even experience hallucinations (Shalala). 4The disease of bipolar itself is classified as Type I and Type II. Type I are thosethat have had prior episodes of mania. One percent of Americans are diagnosed with this. Type II are those that have hypomania phases only (Shalala). A very small percentage (.6)of Americans have Type II. 5Bipolar disorder affects men and women equally. There is no discrimination whenit comes to mental illness (MDA). Cycling is defined by the shifts from one phase toanother. Women are more prone to the more rapid cycling. This is due to the differenthormone changes in the female body. A male is apt to cycle every two to four years, whilea female may cycle four or more times annually (Shalala). 6The best way to understand bipolar is to learn about the different phases that anindividual experiences. There are four different phases: depressive, manic, hypomaniaand mixed episode (APA). 7The depressive phase can last for several months. The patient will show depressedbehavior daily, weight loss, diminished pleasure, fatigue, feelings of worthlessness, lack ofconcentration, restlessness, insomnia or hypersomnia (over sleeping), impaired functioningand suicidal thoughts. These symptoms are present without any evidence of drug oralcohol abuse (Long). Any thoughts of death or suicide should be taken seriously. 8The word mania comes from the French and means crazed or frenzied (Shalala). In the manic phase, the individual sleeps only a few hours, yet is feels perfectly rested. They tend to be talkative, distracted and overly goal-oriented. Unfortunately, they seldomfollow through with their goals. Pleasurable activities become very important, particularlythose that involve high risk. The ego becomes inflated beyond reality and their thoughtsand ideas race continuously (Long). 9Hypomania is a much milder form of mania. In this phase, the individual can easilyfall into a deep depression or escalate into full-blown mania (APA). 10The last phase, mixed episode, is when an individual shows symptoms from bothmanic and depressive phases. 11There are many different theories on what causes bipolar disorder. There seems tobe a connection with family prevalence. Those with a parent with the disorder have a onein seven chance of being bipolar themselves. An earlier age of onset is typical in thesecases. the typical age of onset is adolescent and earlier adulthood (Shalala). 12Other probable causes are biochemistry, biological clocks and psychological stress. It is known that those with bipolar disorder are more vulnerable to emotional and physicalstress (APA). 13The diagnosis of bipolar disorder typically takes up to eight years. Cliniciansmistakenly diagnose depression, anxiety, schizophrenia or paranoia. Inappropriatetreatments only make the disorder worse. Anti-depressants lift the patient into the manicphase and anti-anxiety drugs such as Valium or Xanax depress the patient. Psychotherapyalone does not help (Shalala). .u385ad3b1f96b4eb9606c9a0fb0a8e63b , .u385ad3b1f96b4eb9606c9a0fb0a8e63b .postImageUrl , .u385ad3b1f96b4eb9606c9a0fb0a8e63b .centered-text-area { min-height: 80px; position: relative; } .u385ad3b1f96b4eb9606c9a0fb0a8e63b , .u385ad3b1f96b4eb9606c9a0fb0a8e63b:hover , .u385ad3b1f96b4eb9606c9a0fb0a8e63b:visited , .u385ad3b1f96b4eb9606c9a0fb0a8e63b:active { border:0!important; } .u385ad3b1f96b4eb9606c9a0fb0a8e63b .clearfix:after { content: ""; display: table; clear: both; } .u385ad3b1f96b4eb9606c9a0fb0a8e63b { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u385ad3b1f96b4eb9606c9a0fb0a8e63b:active , .u385ad3b1f96b4eb9606c9a0fb0a8e63b:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u385ad3b1f96b4eb9606c9a0fb0a8e63b .centered-text-area { width: 100%; position: relative ; } .u385ad3b1f96b4eb9606c9a0fb0a8e63b .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u385ad3b1f96b4eb9606c9a0fb0a8e63b .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u385ad3b1f96b4eb9606c9a0fb0a8e63b .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u385ad3b1f96b4eb9606c9a0fb0a8e63b:hover .ctaButton { background-color: #34495E!important; } .u385ad3b1f96b4eb9606c9a0fb0a8e63b .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u385ad3b1f96b4eb9606c9a0fb0a8e63b .u385ad3b1f96b4eb9606c9a0fb0a8e63b-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u385ad3b1f96b4eb9606c9a0fb0a8e63b:after { content: ""; display: block; clear: both; } READ: Alexander The Great Essay14There are solutions for the bipolar patient. Education is the most important. Notonly the patient needs to be educated, but also those close to them. Understanding whysomeone is bipolar and what symptoms to watch for is the first step in helping theindividual get better and maintain a healthy balance (Francell). 15Medications are prescribed to the patients to balance the chemicals in the brain. The most prescribed drug is Lithium. It acts as a mood stabilizer and is often used inconjunction with an anti-depressant such as Paxil or Zoloft. Other mood Stabilizers areTegretol and Depakote. These medications require close monitoring of the levels in theblood to prevent toxicity (Parikh). Medications are most likely needed for a lifetime tomaintain remission (APA). 16When medications fail to work, electoconvulsive therapy is appropriate. Far frombeing cruel and inhuman, the electric currents have shown positive responses in patients(Parikh). 17Psychotherapy in conjunction with medication is a useful aid in helping bipolarsdeal with emotional and physical stresses. The years lost to the disorder before diagnosiscan be dealt with. Support groups also help the individual share the fears and concerns(Francell). 18Proper treatment of bipolar disorder prevents suicide, substance abuse andsocial/personal problems.

Lab Report on Ideal Gas Law Essay Example

Lab Report on Ideal Gas Law Paper We then poured the water back into the test tube and placed the tube into the bucket with the opening upwards, turning the open end downwards after the tube was fully submerged beneath he surface. We then placed the canister directly below the opening of the test tube, and released the gas so that the bubbles rose into the test tube. Next, we used a cork whose head was larger than the opening of the test tube to block off the opening (without changing the pressure inside of the tube), so that we could transport the remaining water to a graduated cylinder. When doing this, it was very important that the water level inside of the tube was equal to that of the surrounding water in the bucket, because that ensured that since the eater pressure in the tube was the same as that of the surrounding water, the pressure of the gas would be the same as that of the surrounding air. Thus, we recorded the gas pressure to be the same as the pressure in the room, which was calculated to be 763. 0 meg. We poured the remaining water from the test tube into a graduated cylinder to calculate the difference between the original water volume and the volume remaining, because this difference was equal to the volume of the gas released. Next, we blow-dried and shook the canister to get rid the extra mass that would eave been added by any water that had clung onto it while it was in the bucket, and weighed the canister again. We subtracted this mass from the original mass of the canister to find out the mass of gas released.

ICC) from the total pressure of the gas (763. 0 meg). With the pressure of the unknown gas lone, we were ready to plug our values into the IV=nor equation. Solving for n, we were able to determine how many moles of the gas we had used, so we only had to divide the mass of gas used by the moles to calculate the molar mass of the gas (in grams per mole). With the molar mass of the gas, we were able to identify the gas. 2. Results: Below are the values we recorded for each step in the experiment, as well as the calculations we made to come up with the molar mass of the unknown gas. Thus, the unknown gas was butane, CHICHI, whose molar mass is about 58. G/ mol. 3. Discussion: The theory behind our experiment was to find each necessary factor in the simplest, most accurate way. The most difficult part was figuring out how to catch all of the gas that we released, and to measure the volume of that gas precisely. The method we used was very effective because we were able to see the movement of the gas, and we were therefore able to control its entry into the test tube. Our results were pretty accurate, but there was some room for error. Below are the calculations for the percent error of our molar mass assortment. Some of the sources of error came from possible procedural problems, while others came due to the theoretical limitations of the experiment. One of the procedural difficulties we may have encountered was that there might have still been some water left on the canister when we weighed it the second time. Because the second mass of the canister would have the added mass of the water, the difference between the original mass and the mass after the gas had been released would have been smaller. Thus, we would have recorded a lower ass of gas released, so the molar mass calculation would have been lower because the numerator of the equation would have been smaller. Perhaps we could have blow-dried the canister for a longer period of time until we were absolutely sure that no water remained. Another procedural problem was the balance we used. Because it only measures to the hundredths place, we recorded the mass of the gas released to only one significant figure. Because of this, we were limited to only one significant figure in our calculation of the molar mass, so although we would have had an answer of 52. G/mol, we had to round down to 50 g/mol, which led to a greater percent error. The theoretical difficulties arose because we were applying the ideal gas law to a real gas. So, for example, while ideal gas particles have elasticity and dont lose speed or energy when they collide, the particles of a real gas do lose energy and speed, and this decrease leads to lower pressure. Also, ideal gases do not have any intermolecular forces, and the volume of the particles of an ideal gas can be ignored, but with a real gas, the particle size makes a difference. Because butane molecules are so large ND exist in a state very close to liquid form, we know that there are very strong dispersion forces holding the molecules together. Larger molecules have more momentary dipoles, and thus a stronger attraction, so because the molecules are held so close together, the volume we recorded was smaller than it would have been if butane were an ideal gas. However, despite these errors, our calculated molar mass was not very far from the actual molar mass of butane gas, so we did a relatively good job of controlling these variables that could have greatly affected our results.
