JEE Mains
Joint Entrance Examination – Main (JEE-Main), formerly known as the All India Engineering Entrance Examination (AIEEE), is an Indian standardized computer-based test for admission to many technical undergraduate courses in engineering, architecture, and planning across colleges in India. The exam is carried out by the National Testing Agency (NTA) for admission to B.Tech, B.Arch, etc. courses in premier technical institutes such as the National Institutes of Technology (NIT) and Indian Institutes of Information Technology (IIIT), which are based on the rank achieved in the JEE-Main. It is generally conducted twice a year. Since 2019, the JEE has been conducted fully in online mode as a computerized test.
The core committee of the NTA decides the syllabus for the 2023 examination. Every year, lakhs of aspiring candidates appear for JEE to get admission to the most prestigious institutions in India for B.Tech, B.Arch, and B.Planning courses.
For better understanding and easy preparation for JEE Mains, a student needs to know the entire exam pattern, syllabus, and topic-wise weightage. The JEE 2023 syllabus consists of topics mostly from NCERT books for 11th and 12th grade Physics, Chemistry, and Mathematics subjects. By using the JEE 2023 chapter-wise weightage of the syllabus, the students will be able to know the topics that need to be focused on and prepare for NTA JEE Main 2023 accordingly . However, there is some variation in the syllabus and weightage of JEE Main 2023.

FAQ: JEE 2023 Syllabus with Weightage
1. Is Ncert enough for inorganic chemistry?
NCERT books are considered the best when it comes to the preparation of JEE Mains and JEE Advance. A lot of questions come directly from NCERT books. However, for other parts of chemistry, such as Physical chemistry, students can refer to other learning materials and books specially created for JEE preparation.
2. Which subject is very important in IIT?
In JEE, all three subjects are given equal importance as they have an equal weightage of 33.33%. So students are expected to give proper time for preparation for all subjects: physics, chemistry, and maths.
3. Is the 2023 JEE syllabus reduced?
The JEE 2023 syllabus consists of chapters and topics from classes 11 and 12 in physics, chemistry, and math that students must cover. However, JEE syllabus 2023 is the same as the previous year, and there are no changes made or no reductions made in the syllabus.
Conclusion:
This article can help students get an overview of JEE Mains exam pattern, syllabus, and weightage. Paper 1 is for students who wish to take admission in B.E or B.Tech courses. Paper 2 is for students who want to take B.Plan or B.Arch courses. Understanding the syllabus is an important factor before starting to prepare for JEE Mains 2023.
