If my overall math grade in math is a 68, if i score a test worth 25% of my grade, and score a 100 on it what will be my new overall math grade

To calculate your new overall math grade, you need to first determine how much the test score will contribute to your overall grade. Since the test is worth 25% of your grade, you can calculate its contribution as follows:

0.25 x 100 = 25

Next, you need to calculate your overall grade after adding the test score:

New overall grade = Current grade + Test contribution
New overall grade = 68 + 25
New overall grade = 93

Therefore, if you score a 100 on the test worth 25% of your grade, your new overall math grade will be 93.
