Dear Student,

For JENPAS UG 2025, most of the questions in Physics, Chemistry, and Biology come from your Class 11 and 12 NCERT syllabus. Focus more on Biology, as it carries the highest weightage.

Biology: Human physiology, genetics, ecology, reproduction, diversity of living organisms, cell biology.
Chemistry: Organic chemistry basics, biomolecules, chemical bonding, equilibrium, coordination compounds.
Physics: Mechanics, optics, waves, laws of motion, thermodynamics, modern physics.

Stick to NCERTs for concepts and practice MCQs daily. Biology should be your top priority, but don’t ignore the basics of Physics and Chemistry.

Thank You
