So, it is important to be as prepared as possible for the final exam. • As with studying for any other test, begin studying well before the final exam. Depending on your comfort level with the material, you may need to begin studying up to three weeks before the final. • Do not try to memorize everything you learned in the course the entire semester. This can cause some students to panic or freeze from information overload during the final exam. Instead, to help you focus on your studying, you can ask your instructor what subject matter you should expect to see on the final. • Be sure to study all material that will be on the final exam. Include material that will be on the final but has not yet been covered in class. • You can form a final exam study group. As with any other study group, do not use the group for excessive socializing. The group should come up with sample final exam problems. Show the instructor your sample problems to make sure the group is on track. Then work together to make sure that each member of the group knows how to solve these problems. • As with preparing for any other test, try to get a good night’s rest the night before the final exam. Do not stay up all night cramming. Eat sensibly before the final. • Be sure to show up for the final exam. Most instructors give failing grades to students who do not take the final, regardless of their grade before the final. • For tips on taking the final exam, see Taking a Test in the Chapter 6 Summary.
