Instructions: Type in the grades you’ve received, along with the weights they’ll have in the determination of your overall average. Then, if you want, fill in one or both of the fields embedded in the questions marked ‘OPTIONAL:’. After you press ‘Compute’, the results will show your average so far, as well as the answer(s) to any question(s) whose embedded fields you filled in.

Every grade you enter must be a non-negative number, and every percentage you enter must be a positive number.
