Needs more options – Grades 3 Review

I'm a high school student and my school averages grades by formative=40% of final grade and summative=60% (the only summative grades are tests and projects). This app asked the weight of each assignment, but we don't have that at my school, so I put 40 and 60 as "weights". This does not yield accurate averages--I already have PowerSchool as a guide for my grades. They need to have an option for formative & summative ratio. I live in Louisiana and every school in the state averages grades like that... Not just me.PLEASE MAKE AN OPTION FOR THIS!?
