If the exam is a
trial or class test, not a final exam, use it to improve your knowledge for the
final exam. Find out what you don't know so you can learn it for the final
exam. Compare your answers to other students who get good marks.
If
possible, keep a record of questions and record the correct answers to
questions you get wrong so you have the right answers when revising. Discuss
any questions/answers you do not understand with your teacher.
