# JEE Main Maths Syllabus 2021 – Topics, Weightage, Books, Preparation Tips

Many students think that Mathematics is a tough nut to crack. However, maths can be a very scoring subject as, if attempted properly and with enough preparation, you can even score full marks in this subject. The exam is totally based on formulas and calculations. As compared to the other two subjects, the syllabus of Mathematics is the same for both the JEE Main Exam and the Board examination. Aspirants who want to get complete and detailed information about the maths syllabus of the examination have come to the right place. This article will give you complete information about the JEE Main Maths Syllabus 2021
