The first sentence of the introduction should pique your reader`s interest and curiosity. This sentence is sometimes called the hook. It might be an intriguing question, a surprising fact, or a bold statement emphasizing the relevance of the topic.
Define a topic: If you`re allowed to choose your own topic, try to pick something that you already know a bit about and that will hold your interest.
If you did your best to write a complete, clear, and insightful essay within the time allotted, you should have nothing to worry about.
Some students react to the time pressure of essay exams by scribbling down their introduction as soon as they`ve read the question and figuring out their points as they go. While it might seem counter-intuitive, taking five or ten minutes before you start writing in order to draw up a plan will be an enormous time saver.
Do your research: Read primary and secondary sources and take notes to help you work out your position and angle on the topic. You`ll use these as evidence for your points.
Come up with a thesis: The thesis is the central point or argument that you want to make. A clear thesis is essential for a focused essay—you should keep referring back to it as you write.
