definitely happened to me...i guess it really depends on one's self discipline...but then again, the concentration time span of people varies for each person...while one can study continuously for a straight two-hour, another can probably study effectively for 1 hour, then probably take 15 mins break before continuing to study for another hour...

as for me, my effective study hours during working days are probably around 2 hours at night (normally around 11 p.m. - 1 a.m.), while during weekends, probably around 5-6 hours max, which are broken down to 2 hours in the morning, 2 hours in the afternoon and 2 hours at night (but it's flexible, depending on my activities during the weekends)...

hope you find your ideal study hours and stick to them...good luck!
