Hello candidate,

The most basic and the most common difference between the JEE Mains and the JEE Advanced Examination is the difficulty level of the questions within the same syllabus and their practice.

In the Mains paper, your conceptual knowledge plays a key part in deciding your overall score, but as we shift to the Advanced Examination your preparation of both knowledge as well as practice-on-paper plays the role to make the cut eventually.

Good Luck!!
