No, I will not advise it. NCERT is just the sllybus for jee mains and advanced.  You can take inorganic of NCERT enough for jee mains but not jee advanced.  Rest of all subjects you need to learn from other source.

Ncert is reffered only with the purpose of building basic concepts. It is not sufficient for any of the two exam.

Hope it helps

Hii Abhijit!
NCERT should be the base or the core which you should rely on. But, just NCERT will not help you get cracking marks. You ought to study from different books, may it be previous year question papers or question banks, or any study material from a reknowned institute. This will help you gain good marks. But, you should not go on reading everything. Know your syllabus and pattern well and then study. Smartwork is the key to success. Hope this helps.
Good luck!
