Image from store PowerSchool Grade Calculator
Description from store This extension will average out your grades on PowerSchool to give you an average if the school has turned it off. It also gets your GPA on the main page, past grades, and can get weighted grades. It should work for every school's site, if it doesn't, click "support", and contact me, and I'll try to figure it out. Please note: This app is made by me independent of Powerschool, and is in no way affiliated with Powerschool. View source code and changelog here: https://github.com/kyleai/getGrade
