How weighted grades work

Each category contributes its score × weight; the total divided by the weight covered is your current grade. For the final-exam math: if the final is worth w% and you're sitting at G%, finishing with target T% requires (T − G×(1−w/100)) ÷ (w/100) on the exam. Anything over 100% is mathematically out of reach — and at 0% the grade may already be secured. All of it runs in your browser, free forever. Need a custom tool for your school or team?
