The National Testing Agency being the examination conducting authority released its syllabus along with the notification. However, JEE Main 2021 Registration Dates along with exams dates have been released by the authority. Talking about the syllabus of JEE Main Examinations, NTA has also released the syllabus of the newly added Paper 3 for admission to B. Planning course. The complete knowledge of JEE Main Syllabus 2021 would help students understand access the syllabus in the rightest manner. Students appearing for JEE Main Exam must be aware of subject wise important concepts and topics from which the question paper is prepared.
One question that arises while preparing for JEE Main Exam is "What is JEE Main Exam Syllabus?". With the correct knowledge of Syllabus, students can focus on right things and plan a strategy to qualify the examination. Since there are various topics that require more time and attention than the other topics, a planned activity can help students prepare in an efficient way.

Difference between JEE Main and JEE Advanced Syllabus
Most of the topics in both exams are common, but if you look at the JEE Main and JEE Advanced curriculum, you will find that practical topics in physics and chemistry are included in the JEE Advanced curriculum. they are contained in JEE Main, but not in JEE Advanced and vice versa.
JEE Main Syllabus

The JEE Main Curriculum includes the physics, chemistry and math curriculum of CBSE grades 11 and 12.

Topics such as electronic devices, electromagnetic waves and communication systems are included. in main JEE, but not asked in Advanced JEE.

Similarly, some of the math topics such as sets, relationships and functions, statistics and probability, trigonometry, and math thinking are in the Main JEE but not in the Advanced JEE. In chemistry, topics such as biomolecules and chemistry in everyday life are included in the JEE core program, but not in the JEE advanced curriculum.

The test enforcement authority NTA has created the complete JEE Main 2021 program.
JEE Advanced Syllabus

In contrast to the core syllabus of JEE Main, the syllabus of JEE Advanced consists of some additional topics in addition to the curriculum of class 12^{th}.

The syllabus of JEE does not contain some of the advanced JEE topics such as thermal physics in Advanced JEE but is not queried in the JEE Main Syllabus.

Similarly, electrochemistry is included in JEE Advanced, but not in JEE main.

Most of the questions in JEE Advanced are derived. While the questions in JEE Main are application based.
