What is the difference between JEE Main and JEE Advanced?

SupVerified answer

JEE Main is the first stage exam that opens doors to NITs, IIITs, and other engineering colleges. JEE Advanced is tougher and only for those who clear Main, and it is your shot at the IITs. Main happens in January and April, while Advanced is in May. Think of Main as your gateway and Advanced as the premium tier.
