hope you are doing good

NCERT is enough for JEE mains but for JEE advanced you should refer other books as well.

you can buy a reference book name jd lee.

for advance you should buy a reference book cause the hardness level of advance questions of inorganic chemistry is much tough then jee. you can't tackle that question with NCERT book level. you have to study very hard and very deep inorganic chemistry for advance

hope this is helpful for you.

best of luck
