FAQ

Can weights exceed 100%?

No. If your syllabus lists extra categories, add them to the calculator so the total equals 100%.

What if result is over 100%?

It means the target grade is mathematically impossible with current scores—either aim for a lower course grade or seek additional points.

Do I need all components?

No. Set both the score and weight to 0 for any assessment that does not exist in your course.

Can I include participation or quizzes?

Yes—treat each additional category as part of the project section or average them into the existing scores before entering.

Does this account for curved grades?

No. Curves, drops, or bonus assignments require manual adjustments based on your instructor's policy.

Additional Information

  • Add up the weights for all components (including the final) to confirm they equal 100%; adjust if your course uses a different structure.
  • If the required score is above 100%, speak with your instructor about extra credit or grading policies to set realistic expectations.
  • Use the result to map out study time, office hour visits, or tutoring sessions before exam week arrives.
