Depends but with Objective type paper u could avoid ie irodov . But have to tell u it's very though provoking book if done properly and would give u a lot of confidence boost doing it.
look i did irodov until i realised that i was not any better than the rest.. it is a problem book ONLY based on calculus..it is important to know how to handle such things. so my advice is:
read all the sums. but only solve those sums which you feel are different from the ones that you have already solved..
here is a momentary list:
in mechanics follow what i said. it is unimportant to do all the sums in mech. most of them will be applications of a = vdv/dx and so on.. they are not concept sums.. they just teach you how to solve really shitty looking sums in a simple way.
in electrostatics, do AS MANY as you can... since electrostatics is almost always asked as a calculus related prob even in JEE.
for waves, optics.. just leave it
for thermodynamics, do only first law (DO ALL SUMS V IMP) leave second law.
well thats it for now. but listen, leave irodov for some time before you start.. it can be very difficult if u r a beginner. i myself did it only around December of the first year. then i had some knowledge of differential calculus. use a solution book if you need it. i reccomend arihant solution, as thay are well explained, and they give extra sums of their own.. but they r slightly expensive.
rahul i suggest that u defnitely do mech and electro frm that book. If u feel that it is only calculus book as many do u(including me) could go for aptitude probs in phy by s.s.krotov.(some portions out of syllb but selected probs are too good.)
