How Final Exams Affect Your Grade

If the final is worth 20%, then 80% of the course grade is already represented by earlier work.

A high final score can help, but it only applies to the final's share of the course.

A 15% final may not change a grade from a C to an A, but it can decide whether an 89 becomes a 90.

That is why final exam planning is most useful when your target is close to your current grade.

A required final score gives you a concrete study target. It also tells you when a goal is not reachable on the final alone.

If the required score is over 100, look for realistic options instead of relying on impossible math.

With a current grade of 84 and a target of 88, a 30% final requires 97.3. With a 15% final, the required score is 110.7, which is not reachable without adjustments.

Use the grade shown in your current weighted gradebook. A raw average can make the required final score look too high or too low.

Can a final exam save my grade?

Sometimes, but only within the weight of the final. A larger final weight gives more room to move.

What if the required final score is above 100?

The target is not reachable on the final alone under the numbers entered.

Can a final exam lower my grade?

Yes. A low final score lowers the weighted portion assigned to the final.

Should I include extra credit?

Only include it if your instructor has already explained how it affects the final course grade.
