# How to Calculate Grade Needed for Final Exam One of the nerve-racking things about being a student is wondering how well you must do on a final in order to earn a certain grade in your classes. If a student is keeping track of her grades throughout the year, she can predict what she needs to maintain her current grade or to raise it a letter or two. Many teachers give their pupils the percentage breakdown for their assignments by category at the beginning of the year. From this, students can calculate the grades they need for their final exam.

Determine the average grade of each assignment category. Generally, teachers assign grades for things such as homework, quizzes, exams and the final exam. Separate these grades by category and find the average grade for each category.

Multiply the average grade for each category by the percentage of your final grade assigned by the teacher. Therefore, if your homework grade is 20 percent of your final grade, and your average grade for your homework is 80 percent, you must multiply 80 by 20 percent. For instance, 80 x 20 percent (or 0.20) = 16. Repeat this for each assignment category and write down the product for each category.
