JEE 2025: Complete Overview and Cheat Sheet

What is JEE?

The Joint Entrance Examination (JEE) is India’s national-level engineering entrance test conducted for admission to top engineering institutions including IITs, NITs, IIITs, and other centrally funded technical institutes (CFTIs). It is conducted in two phases:

• JEE Main: Conducted by NTA, for admission to NITs, IIITs, and qualifying for JEE Advanced.
• JEE Advanced: Conducted by IITs, for admission to IITs.

JEE Main 2025 Exam Pattern
