JEE Subject Analysis: Breakdown of Physics, Chemistry, and Math for IIT Entrance

When you’re preparing for the JEE, India’s toughest engineering entrance exam that filters over a million students for just a few thousand seats. Also known as Joint Entrance Examination, it’s not just about hard work—it’s about knowing where to focus. The real secret isn’t studying more. It’s studying the right things in the right order.

JEE Main, the first stage of the exam, tests your grasp of core concepts across Physics, Chemistry, and Math. Also known as JEE Paper 1, it’s the gatekeeper to JEE Advanced. And JEE Advanced, the even harder second stage that only the top 2.5% qualify for. Also known as IIT entrance exam, this is where real subject mastery is tested. You can’t wing it. Each subject has its own traps, weightage, and patterns.

In Math, calculus and algebra eat up nearly 40% of the paper. Vectors, 3D geometry, and probability show up every year—don’t skip them. Physics is all about mechanics and electromagnetism. If you can’t solve a pulley system or a capacitor circuit fast, you’re losing time. Chemistry? Organic reactions are non-negotiable. Inorganic? Memorize the periodic table trends—no shortcuts. Physical chemistry? It’s all about formulas and units. Get those right, and you’re halfway there.

Most students waste months on rare topics that barely appear. But if you look at the last five years of papers, the same 15 topics repeat in every subject. That’s your target. You don’t need to master everything. You need to master what matters.

This collection of posts gives you real breakdowns—not guesses. You’ll find how to prioritize topics, what questions actually come up, and how to spot patterns before exam day. No theory. No fluff. Just what works for students who cleared JEE.
