i am using resnick halliday walker and concepts of physics for physics. is that enough for theory part of class 12th unit tests and final? do i need to take something like dinesh or pradeep's as well (i don't want to take)? i don't want to lose a single mark in theory part in any exam, please suggest.

It would be enough for your exams but if u r not able to understand u caan try h.c.verma it is best for other entrance exams...

:-)

Well sameer, H.c. verma is really a nice book for preparing for entrances or if uwnt to clear your entrances but if u have to bring nice percentage in 12th then i shud do ncert....
