What cles do I have to p in the 8th grade to be promoted to the 9th grade?

I'm failing social studies and one exploration cl (career explorations). I also have D's in my english, math, and P.E cles. (home school was freaking hard...who has P.E. in homeschool anyway?) Anyways, I live in the clark county school district (Las Vegas) and if you know if im ping or not PLEASE tell me, I've already contacted my school but they're taking to long to respond. Thanks.
