That idea is introduced in a topic sentence. The topic sentence should generally lead on from the previous paragraph and introduce the point to be made in this paragraph. Transition words can be used to create clear connections between sentences.
Once you hand your exam to the professor, relax! It`s easy to work yourself up after an essay exam when you didn`t get the chance to read your work over or you feel like your arguments were weak.
It`s important to give context that will help your reader understand your argument. This might involve providing background information, giving an overview of important academic work or debates on the topic, and explaining difficult terms. Don`t provide too much detail in the introduction—you can elaborate in the body of your essay.
Start planning if you can. Although the situation described above sometimes occurs, it`s also very common for professors to give their students a fairly detailed idea of what an essay question will involve in advance of the test day.
For example, if you`ve been assigned a five-paragraph expository essay for a high school class, you`ll probably spend the most time on the writing stage; for a college-level argumentative essay, on the other hand, you`ll need to spend more time researching your topic and developing an original argument before you start writing.
On the topic of planning, it`s important to sketch out an idea of how long you want to spend on each section of your essay. If you know the number of paragraphs you`ll need to write ahead of time, you can do this before the exam even starts!
