If you have two main points in your thesis, three or five main sections might not work for your research paper. If the assignment asks you to introduce a topic, explain different opinions on the topic, and then choose and explain your opinion, then your paper probably needs three main sections, one for each of those objectives.
You don’t have to read in-full everything ever written about your topic. In fact, you probably can’t. Get comfortable reading through things quickly. Learn how to identify key points and arguments without getting bogged down and reading every word.
If you want to find helpful and reliable sources of information, the library is literally the best place to look around. There are numerous books, published articles, journals and etc. that you can choose from about your chosen topic.
Once you reread your first draft over and over and make the necessary changes you feel you should make, it is time to write your final draft. Make sure that all the vital information is included and your paragraphs and sentences make sense and has a steady and natural flow all throughout.
Use the guidelines given by your instructor to help pick your paper topic. If you have a topic that you love, but you’re having trouble fitting it into the guidelines, choose another topic. It will be easier on you in the long run to write about a topic that fits the assignment.
