If you are to come out of a NET that traps you. Stratagem.

This article is purported to be helpful towards those who take Indian “after the university” entrance exam known as NET (National Eligibility test governed by CSIR; Council of Scientific and Industrial Research) which is held twice every year.

NET for science subjects is known as CSIR-NET and arts/humanities as UGC-NET. They are conducted at different times and by different agencies.

Manmohan sir, I want to qualify net. … any suggestions ?

Find an algorithm at the end for a quicker assimilation of the strategies given here. Both pdf and jpg are available.

I am assuming you will take the test in June 2018.

Solve 10 previous papers thoroughly.

Make a categorization of subject wise weightage: eg mathematical physics, quantum mechanics, thermodynamics etc.

Set yourself a good score based on what you think you can certainly achieve. Make a 15% increase and make that your target.

See your strongest subjects and make a plan which ones you want to be thoroughly prepared about so you can arrive your target.

Never attempt a question, unless you are very sure of it. Negative marks in net can ruin your chances. (By attempt I mean: select the choice)

Decide in which section you want to score how much.

In section A (total marks 30) try to achieve full marks, except a few daunting questions. Getting 22 (11 questions right, assuming no negative score) seems a good idea. In section
