how will make we good.

It depends on your class timing

for in general :

if ;
class timing :7-9hrs per day (incl.sunday)
then you must atleast try to study 5hrs apart from the class time

for example:

class time: 1pm to 9pm
it takes on an average 30min to reach your class .

then you need to leave by 12:30 which means atleast by 11:45 or 12 you need to leave your studies and have some food .fresh up and leave for classess

so try to get up by 5:15 and fron 5:30 to 11:30 you can study and then routine yourself ..with some snack break etc still you get effective 5hr of study
