I am failing health!?

today in health cl, my teacher told everyones averages outloud. He didnt say, which grades were whos. Most of them were under 65 (failing) like, 20's, 30's etc. at my school, anything under 65 is failing. the highest grade was like, 76 and my paretns are gonna ground my for life, and be soooooo disapointed in me if i failed. and i cant take it when my parents are disapointed in me. every time they are, i think about commiting suicide, but thats not the point. i get better grades in eveything else! my average overall is around a 90 or 88 or something. but if i read my report card, and the grade for health is failing, i am gonna break down crying right in my homeroom. and i will be soo embaraced. is there any way that i can make sure that i did not fail? and i could use some sympathy! please. thanx
