Replying to Skiing and school... the impossible balance..

so basically when its not ski season i usually get pretty good grades in school, a's and b's.. but now that ski season is well underway, my gpa goes down the shitter, and i only have 3 classes! my parents think its sad, but i get out of school at 11am everyday and head up the mountain to get my jump and my jib on.. anyway, i talked to my teachers today and i have 2 f's and 1 c..
i'm not really lookin for solutions, i'm just bored.. as a matter of fact i should probably be doing my homework right now but i dont really want to.. so yea anybody got any input?
