Any and every compitative exams asses only and only 2 factors..
- How good your basics are..
- How clear your concept are..
Stress and overstudying will never help. Believe me.. Seen it.. done it.
Enjoy your new found freedom because college life never comes back.
Having said that.. make sure to be really thorough with your textbook.. and by textbook I definately do not mean guide books, reference books or shortcut versions like solved papers and handbooks.
But do refer to them once in awhile, because they too contain vital informations many a time.
If making notes is not possible ( that is if you are as lazy as me) use sticky notes to jot down the special points and paste them on the relevant chapter pages.
