JEE Main is for those candidates who wish to get into BE or B.Tech courses in the National Institutes of Technology (NITs), Indian Institutes of Information Technology (IIITs), other Centrally Funded Technical Institutes (CFTIs) and engineering colleges of the participating states. The JEE Main is also the eligibility test that allows students to give the JEE Advanced exam which eventually leads to admission in either the IITs or the Indian School of Mines (ISM).

The JEE Main is comprised of two papers, namely, Paper 1 and Paper 2. The Paper 1 is for those who would want admission in BE and B.Tech courses and Paper 2 is for those who want admission in B.Arch and B.Planning courses. While Paper 1 is held via the online and offline mode, Paper 2 is held only offline. While applying for the JEE Main exam, the candidates must specify if they want to appear for Paper 1 or Paper 2 or both.

JEE Advanced, on the other hand, is strictly paper-based. The candidates must sit for both Paper 1 and Paper 2 in this exam to get admission into engineering courses. For the candidates who wish to be admitted into architectural courses that IITs offer, the student must clear both Paper 1 and Paper 2 in the exam and then sit for the Architecture Aptitude Test (AAT) which seven zonal IITs conduct. The candidates must register online for AAT after clearing the JEE Advanced exam.
