Usually the final exams cover the material taught during the whole semester, so you will need to review everything from the beginning. The topics covered early on in the semester may have faded from your memory, so make sure to pay extra attention to them. Things like index cards, where you write down the main ideas or definitions, can be very helpful.
Another great way to review the material is to work in study groups. Your memory will absorb the information faster if you talk it through or explain a concept to your study buddy. You can also get a new perspective on the topic if you discuss it within your study group. And finally, one of the most important benefits of studying in groups is that it breaks the routine and makes studying more fun.
Every university and college offers tutoring help throughout the semester and especially before final exams. Tutors are students in their senior year or professor assistants who hold specific hours during the week when anyone can stop by and receive some academic help. Tutors can increase your understanding of a subject and improve your performance on the final exam.
And last but not least, you should sleep and rest well before the finals. It is common for students to cram the night before the final but it is hardly the best strategy. You will be tired and fatigued, and your all-night session may not be productive. Instead, you should study a couple of hours per day each day leading up to finals. Rest and sufficient sleep are your best friends if you are trying to memorize a lot of academic information for the finals.
To summarize, your performance on the final exams depends on a mixture of good preparation, material review, working with study buddies and tutors, as well as being well-rested and energetic. Best of luck!
