Helpful, but one major bug/flaw – Grades for Parents and Students Review

I thought this app was great, and it really could be, but the calculating of your scores doesn't work. When you try to change your scores it will come out with something dumb like me losing a percent when I turn in a homework assignment and get a 3/3. I don't know if this is because it hasn't been perfected yet or what but it's very misleading and could lead to unwanted grades. I'll still use it but don't believe it to be 100% accurate until this bug is fixed.
