Want to know your grade if you don’t do (get a zero) on the final? Since we’re close to the end of the semester, the math is fairly simple: look up the percentage of your overall grade that the final accounts for, subtract that from 100%, and multiply the remainder by your current grade. Look over the example below:

Final = 15%, Current grade = 89.2%

 100% - 15% = 85%

 89.2 * 85% = 75.82% Final grade

You can see by this example that it is important that you at least make an attempt on completing the final. Even a fail on the final that equals only 37% brings the grade back to a “B”, and a low “A” on the final (about 91%) equates to a semester grade of “A”.
