@ mohit 
as far as jee advanced is concerned , it will have all conceptual ques combining from 3-4 concepts . 
so , u need to have a good grasp over the concepts to get good ranks in advanced . 
and for that CONCEPT OF PHY BY H C VERMA IS the bible . that u have to read for sure . 
they are generally sufficient if u can solve each and every problem throughly . 
and some problems in advanced are difficult . so, by keep an side book for problem solving 
PROBLEMS IN PHY BY I E IRODOV . 
ALL THE BEST ..

							Dc panday and hc verma for physics these are very good for numericals and competetive ques you mist purchase and do dc pandey has 5 volumes for both 11th and 12th
