No dear there is not any conflicting point that u had pointed out in my previous post however, u did not get my point.
Friend!There are some topics well can be learnt from lower level books instead of advance one. If u find yourself in confusion then u must go with aforementioned books. Besides, If u look at the paper, now that has been changed into 2 parts one is theoretical and other is objective. It is, therefore, certain to say that objective portion of paper can easily be tackled if u hav good and compact clearance in basic concepts, it is only possible, if we read aforementioned books of low level, along with this u can get good score also from objective portion. After that dear, as I shared u advance level book ,verily, will help u a lot accordingly, but the main thing should be cleared is to understand basic theme of topics subject. If u have no problem in concepts then u may go to opt advance level books.

Dear, I firmly, believe in clearance of concepts instead of cramming.

Regards.
