in my opinion find out what you really want to do with your life i.e. computers, construction, drawing and find out what colleges specialize in that, then from there find what their requirements are. the colleges i'm looking into make me look like a genius when they ask for SATs lol. but seriously just keep like c+ to B average and your good.
the thing that i hate about my district is that when they give you your class rank they take all the weighted classes and make those kids in a lower rank but don't look at GPA so for instance my friend has a GPA of 3.1 and hes in the top 15% meanwhile I have a 3.65 and im like 98 of 401 in my class.
