Hello,

You must be having syllabus of the entrance exam. Prepare as per the syllabus. it might be difficult but you have to do it easy. cover easy chapters then move towards hard ones. make notes, draw figures, flow charts or blocks to remember. when you take a nap , remember or recite the thoeries or principles or rules.

if any chapter is hard and lengthy then read that chapter daily atleast one hour. every time you read, try to understand what it is saying and relate it to real world. try to learn it.. ask why? how? what? when you get to know something new then you will get to know something more related to it.

it is not necessary DU BSc student can do DU MSc. You can do Masters degree even you did MSc in different college. If you don't want to appear entrance then you have to choose private institutes or government colleges for admission. They give admission based on merit. Government college keep a high percentage bar to select candidates.

Hope it helps!
