alright here u go.....
first of all choose whether u want to study late night or early morning..considering early morning as the best..
wake up early at approx 3:30-4:30 in the morning. i know its hard but just try one week and u will see the magic.
first of all start revising the previous day concept for 30 mins. and previous years topics(complex, conic,trigo. i suppose) for 1 hr.. read the concepts and formula daily.
then start ur practice problems and do it in a stretch of 2-3 hrs continuously. u should finish it till max. 10 am.
then the schedule is flexible u may take another session either in day time or late evenings.
u may also have a nap in the day time but it must be controlled and short one.(max. 2and half hrs.) so that u can also study in night.
it is highly recommended that u take two sessions. it will be very helpful. also regularly take some tests from 11th course like the one given in reso. material or at last of each chapter in A Dasgupta.
last but not the least never take stress as "am i doing it right" or "will i be selected or not". if u get bored just watch a movie(something motivational like 300). it will be very refreshing.
BEST OF LUCK......
