If not then, than begin your review at least a week before the exam is scheduled. A small review, one hour daily, for seven days is much better, memory wise, than 7 hours of study the night before the exam. Stay current with the material. Clarify any confusion as soon as you can. Don't forget about previous courses.
Many courses demand knowledge from a previous course to be able to solve a current problem.
IEA will show up in several courses down the line, as well as Chem. of Materials, and Calculus is the common language spoken in all of your science courses. Review current techniques being stressed in the class. Be aware of past techniques used. You could correctly solve a problem, but because you didn't use the asked for theorem, you will not get credit for the answer. Practice with friends throwing the formulas out in front of the study group.
