well my suggestion is whatever books u do,get ur basics n concepts cleared.....that's the secret to crack any exam.i'd suggest :
chem : easiest to score among pcm....do it prorerly
NCERT 4 basic,then do any MCQ book preferably arihant.
maths : NCERT/R.D.Sharma + s.n.dey 4 basic,then do TMH(tata mcgraw-hill).
phy : NCERT + H.C.Verma,then do arihant's D.C.Pandey.
along with these see if u can solve fiitjee's study material preferably rankers study material(RSM).after doing all these even if u get tym,then do the books of arihant specially for a particular section like mechanics in phy,trigo in maths,physical in chem etc otherwise be satisfied with the books above.
wishing u best of luck.....
