Commonly asked questions
Not both are not same. But some topics are similar in JEE Main and JEE Advanced. Students who qualify the JEE Main exam and are among the top 250000 students are eligible to take the JEE Advanced. Due to this reason majority of syllabi are the same, but a few extra topics are added in JEE Advanced.
JEE Main syllabus is based on class 11 and 12 Physics, Chemistry and Maths topics. If you have focused while studying, then it will be easy to prepare for the exam otherwise, you may find it difficult. NCERT textbook is the best for Chemistry and Physics. You can also refer to other books for exam preparation. There are many preparation books suggested by the toppers of Joint Entrance Examination Main.
Students who are in class 12 and would also be appearing in JEE Mains 2026 exam mostly find it difficult to manage both their class/school and JEE studies. However, all these students have an advantage over others/droppers aspirants as there are many common topics in class 12 and JEE.
To benefit, they must identify all the topics that are common and study those first. Secondly, cover the topics that have more weightage in class 12 and complete them. Before a few days of JEE Mains, study specifically for JEE. This way, they can manage both class 12 and JEE efficiently.
