hello,

If you've entered your second year, now is the optimum time to start the preparation for the entrance exams especially if you are a little weak in maths. JNU and DSE exams are not very easy as they put your 3 years of undergraduate Concept learning to test. So it is always better to Start early. Practice alot and check out previous years papers.
