Difference Between JEE Main Paper 1 and Paper 2

Every year, the National Testing Agency (NTA) conducts the Joint Entrance Examination (JEE) Mains, which provides eligible candidates with an opportunity for admission into various undergraduate courses like B.Tech, B.Arch, B.Plan, and B.E. Successful candidates can secure seats in some of the top engineering colleges across India, which includes NITs, IIITs, Government Funded Technical Institutes as well as CFTIs. To excel in this exam, it is important to understand the JEE Main exam pattern thoroughly.

This article covers all the essential details of the JEE Main 2025 exam pattern. Paper 1, which is required for B.Tech admissions, and Paper 2, which is divided into Paper 2A and B.Arch courses and Paper 2B for B.Plan courses, are two essential components of the exam. Scoring well in both papers is vital to qualify for the next step, JEE Advanced, which is a gateway to prestigious IITs and other institutes.

JEE Main Exam Pattern 2025

Below is the JEE Main exam pattern for Paper 1 and Paper 2, which the conducting authority announces on the official website.
