well i didn't either so i sure hope you didn't!
i re-checked and it never actually said that you had to.!
if you did, how much marks do you reckon we would lose?
year 11, i did about 2 hours a day.
now in year 12, doing about 3 hours a day and yes a little stressed, but hopefully ill do fine!
5 hours a day is quite over the top- however people aiming for 99 probs need that amount..
