Candidates appearing in the exam must review all the topics in Physical Chemistry, Organic Chemistry and Inorganic Chemistry. They can check the JEE Main Syllabus 2024 as well as the syllabus of JEE Main 2025 exam as there is no change.

Deleted Syllabus of Mathematics in JEE Main 2025

There has been no removal of topics from the syllabus of Mathematics for JEE Main 2025 exam. Candidates must proceed and prepare all the topics from the JEE Main Mathematics syllabus 2025. These topics include Algebra, Calculus, Geometry, and Statistics. All the other prevalent topics such as Probability, Differential Calculus, and Trigonometry have remained to keep their places so that the section would be tough enough for students and also eligible as per the requirements of the competitive engineering entrance examination. Despite the deletion of topics in JEE main syllabus 2025 mathematics remains unchanged this has been done to allow students to focus on the core topics.

Deleted JEE Main 2024 Syllabus

Though the JEE Main Chemistry syllabus and JEE Main Mathematics syllabus remain unchanged (no deletion of topics) And a similar to the JEE Main syllabus 2024, the candidates appearing in the exam must be aware of the complete syllabus of JEE Main 2024 exam. The National Testing Agency did make some changes in the JEE Main 2024 syllabus.
