Hi aspirant,

No, Only NCERT is not sufficient for cracking jee advanced exam because for that you need to work very hard .

Jee advanced is the competition for admissions into various branches in IIT's. So work for that accordingly rather than looking for any other source.

Also, kindly look for other books and learn the topics in advanced manner because the examination will be tough to crack.

Hope this information will help you .

Thank you and good luck:)
