Read and understand the whole question before beginning to frame an answer.
Develop a short outline (three or four brief lines) to budget the right amount of time to answer each part of the question. The outline can become subheadings for your essay.

Readers try to be fair and considerate with every paper, knowing that it represents a teenager trying to spill his/her guts in 1.5 hours of everything they should have learned during the senior year (in most cases).
