Frequently Asked Questions:

Although there is significant overlap in the topics covered by JEE Main and JEE Advanced, they are not identical. JEE Advanced places a greater emphasis on practical aspects of Physics and Chemistry. It is advisable to have a strong understanding of practicals from CBSE Class 11 and Class 12.

The JEE Advanced exam is conducted as a Computer-Based Test (CBT), meaning it is administered online.

To score well you need to complete 100% of the syllabus of Physics, Chemistry and Mathematics.

The registration window for the JEE Advanced 2025 exam will tentatively open in the last week of April 2025. You can register online on the official website after the registration process starts.
