Hi Aspirant,

You must be very focussed since the beginning of the preparation.try to finish the syllabus as early as possible and after that try to go through the past years paper.For physics i would recommend you to go through HC verma's sums which will help you to build strong concepts after all.NCERT for chemistry would be fine.Try to strategise the objectives of Biology from beginning and get hold of a good previous year's paper book.

Hope it helps!!
