Practice under test conditions
Do practice questions with notes closed and a time limit. It shows what you really know and builds calm for the real thing.
Start a week out
List the topics, rate how confident you feel about each, and spend most of your time on the weakest ones, a little every day.
Sleep counts
Sleep helps the brain hold on to what you studied. An all-nighter usually costs more on test day than the extra hours add.
Do this today
For your next test, list the topics and rate your confidence in each from 1 to 5.
