Exam

It gets down to three crucial points. (I am assuming that the person carrying on this voyage has already cleared his/her Mains exam and knows all the rudiments of all the topics).
1. Chemistry is the key to get a good score. It needs lesser effort compared to the other two subjects and it is very scoring. So one must study the chemistry NCERT book very meticulously, atleast twice in the 30 days.
2. Attempt previous year IIT-JEE question papers and try to do atleast 1 paper in every two days (or maybe a paper every day). Starting from the latest paper and moving backwards. Bingo, at the end of a month you have solved 15 year's question papers (atleast).
3. The most important part while attempting point number 2 is scrutinizing your test and checking for the scope of improvement. If you're not so good at mechanics or calculus, you should probably give more time to it and keep revising these areas to score well.
