JEE Main and JEE Advanced are national-level entrance exams that open the gates to India's top engineering institutions for aspirants. IIT JEE is one of the most important exams for engineering students, which they take to get admission to the program of their choice. JEE Main is the primary test required to get admission to government-sponsored technical colleges like NITs and IIITs, whereas JEE Advanced is primarily required for the IITs.

A candidate must pass JEE Main exam to appear for JEE Advanced. Despite their similarities and interconnections, JEE Main and JEE Advanced differ in several ways, all of which will be discussed here.

Differences in the Exam Pattern

The JEE Main exam is divided into three parts. Students should review the official website for exam pattern, and double-check the curriculum during their preparation. Candidates must evaluate the length of the examination, the language used, and the number of questions on the paper.

The JEE Advanced exam, on the other hand, is divided into two halves. Since the exam pattern hasn't changed considerably over the years, students should review the previous year's exams. 


JEE Main - Paper 1 - Physics, Chemistry, and Mathematics

Paper 2 - Aptitude test, Mathematics, and Drawing

Paper 3 - Mathematics, Aptitude Test, and Planning-Based Objective Type

JEE Advanced - Physics, Chemistry, and Mathematics

Difference in Eligibility Criteria 

JEE Main is a baseline examination that candidates must take to be considered for admission to top engineering institutes.

The JEE Advanced eligibility criteria require the candidate to pass JEE Main.

JEE Advanced - The candidates must have cleared the class 12 examination last year or who are appearing for the exam in the current year are also eligible for JEE Advanced.

Age Limit

JEE Main - The candidates do not have any age limit to appear for JEE Main 2022. Any applicant who cleared class 12th or its equivalent in the current years like 2020, 2021, or appearing in 2022 can apply for JEE Main 2022.

JEE Advanced - The General category students should be born on or after October 1, 1996. Relaxation is provided to candidates of SC/ST/PwD of 5 years

Difference in Syllabus

Physics, Chemistry, and Mathematics subjects from CBSE classes 11 and 12 are included in the JEE Main syllabus. Electronic Devices, Electromagnetic Waves, and Communication Systems are all covered in JEE Main but not in JEE Advanced. For example, JEE Main covers Sets, Relations, and Functions, Statistics and Probability, Trigonometry, and Mathematical Reasoning but not JEE Advanced.

Unlike JEE Main, it includes a few extra courses in addition to the Class 11th and Class 12th syllabus. For example, some of the topics covered in JEE Advanced are not taught in JEE Main, such as Thermal Physics, which is covered in JEE Advanced but not in JEE Main. In the same way, electrochemistry is covered in JEE Advanced but not in JEE Main.


In navigating the distinctions between JEE Main and JEE Advanced, the importance of comprehending eligibility criteria, exam patterns, and syllabi becomes evident. The total number of attempts, subjects covered, and even the language of the exams vary. Whether considering the differences in conducting authorities or the unique qualification criteria, each detail influences an aspirant's journey. Recognizing these nuances aids in strategic preparation. As you embark on the path to these engineering gateways, understanding the divergence between JEE Main and JEE Advanced becomes not just a necessity but a roadmap for success. Prepare wisely, aim high, and embrace the challenges that pave the way to engineering excellence.

FAQs on JEE Main and JEE Advanced: Difference Explained
