According to the Latest JEE Main Physics Syllabus 2025, 80% of JEE Physics syllabus weightage is given to the theory section and 20% to the practical section. Last year, NTA dropped several chapters from physics. The updated JEE Main Physics Syllabus consists of 20 chapters.

  • In this new syllabus pattern, Modern physics, current electricity carries more weight, whereas electrostatics and sound waves have less weight.
  • No change has been made to JEE Main Exam Pattern 2025. A total of 25 questions are asked in the JEE Main Physics Question Paper, 20 MCQs and 5 NATs. Candidates don’t have a choice of answering any 5 questions from NATs.

NTA has completely deleted the JEE Physics chapter on Communication Systems from the syllabus, along with the deletion of other topics. In this article, we will discuss the detailed breakdown of the JEE 2025 Physics syllabus, topic-wise weightage, past years' weightage trend, high-weightage chapters, etc.
