The JEE (Main & Advanced) is a two-tiered entrance program for engineering in India, where JEE Main is the first stage for admission to engineering colleges like NITs, IIITs, and CFTIs, and is also the qualifying exam for JEE Advanced. JEE Advanced is the second stage for admission to Indian Institutes of Technology (IITs) and has additional topics and a more difficult format. Eligibility for both requires a Class 12 qualification, but JEE Advanced is only open to the top 2,50,000 candidates in JEE Main.
