My son never prepare for any test.

The most important one was his 6ht grade SAT. The night before he had a hockey game and he went to sleep at 11:45pm. Next morning we draged him out of bed and went to high school to take the test. The test would decide which classes he will go next school year. He was fine and he got to the best classes his school offer. Even he is in high school now, He never prepare for any test and he has test almost every other day. He told us that if he doesn't know even with study he still will not know (he has hockey three to four night/week). He doesn't want give up his sleep time and hockey to get better score. Anyway he got all "A" for the past final but not perfect score. That is enough for me.
