"I've said all the things" - all the teaching is done.
This is your time to demonstrate what you have learned in the course.
There's no secret to studying or preparing for an exam.
Healthy food, lots of sleep, and physical fitness all play a role.
Organize your notes and assessments. Go over them often, clarifying areas you do not fully comprehend.
If you can't explain a topic to someone else, you aren't ready to be tested on it.
Create a formula sheet for yourself and triple-check the accuracy of the formulas.
Create summarized notes for yourself in a chronological or at least logical order. Do so in an organized fashion - not just random sheets of paper.
Attempt practice questions and verify solutions with classmates or sources.
Do. Not. Cram.
