Ceramics Beginner Class?

My teacher made me load the kiln with over thirty glazed pieces. I'm stressing because I think I might of loaded it wrong. The teacher left me to do it by myself and my classmates wouldn't offer to help. For each shelf are you suppose to use six or eight posts? Any way if I messed up my classmates and teacher are gonna give me hell. Should have never taken this class. All the Art teachers I have met at my school seem like they don't care. I hate Art now and will never again take it
