I want to prepare for M.A.economics entrance held by JNU CEE .Is there any entrance qualified student can please guide me with preparations?

I would suggest you to go through the below provided general tips-

First of all, students need to make a good study plan for preparation. For that, you must have the knowledge about the syllabus and exam pattern.Time management plays a very important role in exam preparation so while preparing the time table must take care that study of one subject should not exceed for 3-4 hour as it can make you stressful.Try to make notes of the important topics as it will help you in last minute study. Before going for the exam, you can revise these notes. Notes written in your own hand writing is easy to understand and revise. Due to the wide syllabus, students get confused from where they need to start preparation. This confusion may leads to stress. So try to find some useful books that contains previous years solved question papers. Apart from study, it is also very important to keep yourself fit and fine. Because of studies, some students starts avoiding their health.

Hope this helps!!!
