Studyin till late night...

I has been after a very long time that I am studying till so late in night i.e. 1:05 in the night. I used to be awake till very late till an year back but in my class 10^th summer vacations I got used to sleeping early and then waking up at like 4:00 AM to study. But, now that the exams are here I will have to sleep late and wake up early. Probably I will sleep in the afternoon so that I dont miss out on my precious sleep. I am doing "Indian Awakening" right now and after that I plan to do "Agriculture" and "Forest and Water Resources" and then if I am able to keep my self awake I will do some Civics as well.
