Frequently Asked Questions
How do weighted grades work?
Each category (exams, homework, projects) counts for a percentage of your final grade. An exam worth 40% affects your grade twice as much as homework worth 20%.
What grade do I need on my final?
Use the formula: Needed = (Desired Grade − Current × (1 − Final Weight)) / Final Weight. For example, to get 90% with current 85% and final worth 30%: (90 − 85×0.7)/0.3 = 101.7%.
What is the difference between weighted and unweighted grades?
Unweighted grades treat all assignments equally. Weighted grades assign different importance to different categories, reflecting that exams typically matter more than homework.
