Important Formulas for JEE Advanced 2024: Mathematics, Physics and Chemistry Formulas

JEE Advanced is a highly difficult engineering admission exam in India that requires extensive preparation as well as mastery of a variety of topics and formulas. Formulas are used to solve difficult problems and equations in physics, chemistry, and mathematics. Candidates taking JEE Advanced must extensively learn and practise formulas in order to perform well in the exam. Students must understand JEE Advanced formulas in this context in order to pass this extremely tough exam. In this article, we'll go over some of the most important JEE Advanced formulas that students need to know in order to do well on the exam.


Circle, 3-D Geometry, Vectors, Trigonometry, Limits, and Application of Derivatives are some of the significant formulas for JEE Advanced in Mathematics. Alternating current, simple harmonic motion, thermodynamics, waves, and wave optics are all significant formulas in physics. Chemical equations, stoichiometry, and gas laws are all significant formulas in chemistry.


Because the JEE syllabus is so wide and comprehensive, it can be difficult to retain all of the concepts and formulas as you progress through your preparation. In this essay, we'll look at some techniques for remembering JEE formulas for a long period, at least till you finish JEE Main and Advanced.

How Can JEE Advanced Formulas Assist?

  • Before you begin your preparations, gather your study materials. 

  • As you prepare for the exam, make separate notes for the relevant formulas for each subject. 

  • These useful notes aid with focusing on the concepts. 

  • It aids in the management of exam time.

  • It improves in calculation.

  • Reduces the possibility of errors.


Differences Between Topics For JEE Advanced and JEE Main

The syllabus for these assessments varies as well. The JEE Main syllabus contains topics from grades 11 and 12 in Mathematics, Physics, and Chemistry. The JEE Advanced test will cover a few extra topics.
