Study Plan

Basic plan is that each chapter is to be completed in 20 days. First 10 days theory portion is to be completed. Next 10 days, some revision of theory portion is to be done and some problems have to be done. In total 20 days all problems in the chapter have to be done. You have to mark all problems which you feel are difficult problems for a revision at a later date and for examinations.
