It can help with grade recovery, target grade planning, final exam planning, weighted category planning, bonus assignments, and checking whether extra credit is enough to reach your goal.

Frequently asked questions

How does extra credit affect my grade?

Extra credit usually adds to your points earned without adding to points possible, which increases your percentage grade.

Can extra credit make my grade over 100%?

It can if your teacher allows scores above 100%. Some grading systems cap scores at 100%, while others allow bonus points above the normal maximum.

How do I calculate extra credit needed for a target grade?

Multiply your target grade by points possible, then subtract your current points earned. The result is the extra credit points needed.

Does weighted extra credit count differently?

Yes. If extra credit is in a weighted category, its course impact depends on the category or assignment weight.
