NCERT is enough for inorganic chemistry. For physical chemistry one must practice sums, that can be be done following any objective book like Engineering Chemistry, or Solved Papers !
For organic Notes and sums are enough as its a vast topic and you need someone experienced to guide you 

hi ria

for the preparation of NEET UG , the only best book is N.C.E.R.T CHEMISTRY , that book is boon for NEET UG , the questions asked in the exam are based on N.C.E.R.T Book , the theory is what that is asked in the questions, the numericals are all explained in N.C.E.R.T book, so i recommend you to go thoroughly chemistry N.C.E.R.T books. beside it you can have practice papers and question banks for more variety of questions, but all answers are found in N.C.E.R.T

the same is true for other subjects like physics and biology
