not to scare u guys or anything, however, i've heard of a few people, or ishould say... i know a few people... who spent their holidays studying, and when the study period before the HSC came, they were so sick of studying, they literally gave up and did'nt study at all, they had had more than enough, and just let fate do the rest................... so yeh. I presume that study everyday is too much. unless if u only do 2-3 hours, however i think that 6 hours 3 days a week is enough, or on an even positive note, 3 hours 3 days a week, unless if ur really thick headed and need loads of time for 1+1 to get through ur head ( just kidding), don't peopl play sports, or have jobs, like over the holidays, or even....... arent' u guys going on holidays?
