Description from store Ever wanted to see how a grade would impact your average in a class? Well that's simple: if it does not use point systems, add up all the points you earned plus the new grade's achieved points then divide by the... Oh wait, that might take a while. That's why this extension was made. You can add fake grades and your class average will automatically update based on the new grade. It even works on categories too!

  • (2022-12-09, v:1.0.4) human person: Not working for some classes and working for others
    Some classes I have I can add in a fake grade and see what it does to the overall score, but other classes this does not come up as an option. Please fix this, the classes they don't work for just so happen to be the ones I want to know
  • (2020-10-03, v:1.0.3) Ceyanna Armbrister: It stopped working for me ):
    When I tell you I loved this extension because it allowed me to know the lowest grade I could get without it effecting my grade. But for some reason, this school year, it just stopped working. I removed it like 7 times and restarted my computer and it still just will not work. Every time I try to add an assignment nothing happens and it doesn't come up like it used too. Pls help me, thank you!
