JEE Main Physics Preparation Strategy

To prepare for the physics section of JEE Main 2027, students should start by solving exercises in the NCERT Books. Students can also solve JEE Main Mock Tests to understand the exam structure and question types, and to feel the pressure set by the NTA.

• Start with NCERT: Read Class 11 and 12 NCERT Physics line by line. Solve all in-text and exercise questions. Most 1-mark or concept-based questions in JEE Main trace back to NCERT.
• Prioritise high-weightage chapters first: Electrostatics, Optics, Rotational Motion, and Modern Physics together can account for 30 to 40% of Physics marks. Master these before moving to lower-weightage chapters.
• Practice numericals daily: Physics cannot be prepared by reading alone. Every chapter must be followed by numerical practice, with at least 50 questions from each high-weightage chapter.
• Unit 20 (Experimental Skills) is free marks: This unit is easy, predictable, and directly based on standard school experiments. Prepare the list of 18 experiments listed in the NTA syllabus and expect 1 to 2 direct questions from here.
• Previous year papers are gold: Solve all JEE Main previous year Physics papers from 2014 to 2026. Physics has the highest percentage of repeated-concept questions among the three subjects.
