Answer:
When taking exams, it's good to study beforehand so that you get a good grade. You need to pay attention, and keep your eyes on your own paper/test/exam. No cheating, and no talking.
A question might come up that you don't understand. For that, it's best to take a breath and really think about it, but if it takes too long, skip the question and come back to it later.
When writing a paragraph, you have to focus on the main thing you're writing. Paragraphs contain five sentences and up. You're sentences don't want to be too short, or too long.
An essay contains many paragraphs, at least five. You have to make sure to not drift off from what you're trying to explain. Keep it steady and make sure it's understandable.
