JEE is a much tougher examination compared to that of the AP EAMCET. So if you are aspiring for the JEE then nope! NCERT Fingertips will not be sufficient. You need to practice other books like JD LEE, OP TANDON, PBAHADUR for the Chemistry and similarly for MATHEMATICS, ML KHANNA, RS AGGARWAL etc.

Now if you are going for the EAMCET then books like NCERT Fingertips along with NCERT books and you can also practice the problems from the previous year question books or anyother study material available online.
