I could do 12hrs it doesnt really make me tired but yes its really tedious and boring I suppose , I study for about 2-3 hrs then I take a break or so for about 15mins-30mins which is pretty efficient
SO yeah I wake up at around 7;00 am everyday and probably sleep at 12;00. But sometimes when i muck around or get lazy I tend to study probably 5-7hrs at minimum, but this week I did about 48 hrs
but i think i didnt use my time wisely
. The thing is, it doesnt' depend how many hours you study, i may study 12hrs a day but I don't use it very efficiently which is an issue
