Choosing the Most Important Subject for JEE: Physics, Chemistry, or Maths?

Jul, 4 2025

Imagine spending years preparing for one of the toughest entrance exams, only to wonder if you put your efforts in the right place. The JEE is notorious for turning even the brightest school toppers into nervous wrecks. Every year, over 1.2 million students sign up, hoping for a ticket to the IITs or NITs. I still remember the heated debates during chai breaks at coaching class: Do you dive head-first into Maths? Should Physics be the main grind? Or is Chemistry the real secret weapon? The truth is, the answer isn’t obvious, but getting this right can make or break your rank.

The Marks Game: What the Numbers Reveal

When you pull out the JEE Main and Advanced paper blueprints, it’s clear each subject – Physics, Chemistry, and Maths – holds the same official weight. On paper, that is. JEE Main has 300 marks in total, split evenly: 100 marks each for Physics, Chemistry, and Maths. That sounds fair, but the devil’s in the details.

Statistics tell an interesting story. If you check the marks distribution from the JEE Advanced 2024, top rankers didn’t always ace every subject. Some scored a near-perfect Chemistry, an average Physics, and a solid Maths paper. Small differences in one subject were often made up by killer performance in another. Check out this breakdown for recent toppers, pulled together in a simple table (data sourced from Success Achievers 2024 report):

Rank	Physics (%)	Chemistry (%)	Maths (%)
1	89	95	87
5	80	93	90
10	71	98	92
50	78	84	88

Spot the pattern? Chemistry often shows the highest scores. But that’s not the whole picture. Why do students crush Chemistry more than the other two? It’s partly because Chemistry has more straightforward, memory-based questions. Physics can throw you curveballs, and Maths loves to sneak in time-consuming calculations. So, if we look at pure marks, Chemistry is statistically the most important subject for JEE, at least for boosting your rank with the least effort.

Why Chemistry Is the Secret Scorer (But Don’t Ignore the Rest)

If you chat with last year’s JEE aspirants or quiz some coaching gurus, they’ll admit it—Chemistry is the scoring subject. Unlike Physics, which can flip your mood with tricky logic puzzles, or Maths, which demands speed and accuracy, Chemistry questions often hug the boundaries of your NCERT textbook.

Here’s why Chemistry deserves your love:

• About 70% of Chemistry questions have direct answers in the NCERT book.
• The questions rarely stretch your imagination; they stick to well-defined concepts.
• Many toppers said Chemistry saved them during “bad” Physics or Maths papers, letting them recover lost ground.
• Memorization pays off—organic and inorganic Chemistry can be conquered with regular revision. Great for last-minute prep.

I’ve seen students like Ishaan’s classmates (my son’s friends) breeze through Chemistry, pocketing 80+ marks in mock tests while groaning at lengthy calculus problems. Chemistry’s reliability doesn’t mean you get to slack with the other two, though. If you ignore Physics and Maths, you’ll hit a ceiling: Chemistry alone can max out at 100 marks. To be a JEE topper, you’ll need to balance comfort with challenge.

The Physics Dilemma: Low Scoring but High Reward

Physics and stress go hand-in-hand for most JEE candidates. It’s the wild card. Here’s the thing: Physics doesn’t reward shallow reading. Those who master concepts, understand derivations, and solve problems daily are the ones who pull ahead. The downside? It’s easy to lose marks fast if your basics are shaky. In JEE Advanced 2024, only about 37% of students scored above 70 in Physics – way fewer than in Chemistry or Maths.

Check these tips if you want Physics on your side:

• Don’t try to cram Physics like Chemistry. Concepts build on each other—miss a step, and the whole structure topples.
• NCERT is a starting point, but practice from books like H.C. Verma and D.C. Pandey for that competitive edge.
• Never skip experimental or application-based questions—these have increased in JEE Advanced and can be major score boosters.
• Build problem-solving stamina. Give yourself timed quizzes to mimic exam pressure.
• Never underestimate units and dimension analysis—sounds trivial, but mistakes here cost crucial marks.

At the end of the day, Physics is like a see-saw. The pay-off is huge if you work on it smartly, but don’t get sucked into solving only tough “IIT-level” problems. Master your basics—half the battle is already won. My neighbor’s son, Aarav, scored low in Physics in all his mocks until the last month. Once he started reviewing only his errors, not his whole book, his scores jumped from 50 to 82—no crazy new strategy, just targeted revision. Sometimes, it’s not about working harder, but smarter.

Maths: The Decider for Top Ranks

Now let’s talk Maths—the field where toppers actually leap ahead of the crowd. Maths rewards practice like no other subject. Want to know a secret? The best JEE ranks are usually clinched when students solve Maths efficiently. Here’s why: in almost every year, Maths has the highest number of attempted questions with partial responses. Most students solve the starter questions, but only those with sharp calculation and time management skills move onto tricky algebra, calculus, and coordinate geometry.

Think you can ‘wing it’ in Maths? The stats say otherwise. The median Maths score in 2024 JEE Main was just 61 out of 100—much lower than expected, because problem variety throws off even seasoned aspirants. Here are a few practical strategies:

• Don’t memorize formulas alone—practice applying them in different ways, particularly with topics like integration and permutations.
• Time yourself when solving mock papers. Maths often gobbles up precious minutes if you aren’t careful.
• Focus on topics with high weightage—coordinate geometry and calculus together make up about 35% of the exam.
• Make a mistake notebook. Every time you mess up a calculation or misinterpret a question, jot it down. Reviewing this just before exams is pure gold.
• Join group study sessions occasionally—explaining solutions out loud helps you find hidden gaps in your thinking.

Maths isn’t just about brute force; it’s about building speed and trust in your gut instincts. I tell Ishaan to treat each Maths mock like a speed run—not just about acing problems, but shaving off every wasted second.

So, which subject REALLY matters the most for JEE? Statistically, Chemistry gives you the best odds for easy marks. But to get a top rank—or, say, a top 1000 finish—it’s the synergy of all three that separates the winners from the rest. Toppers use Chemistry as their solid backup, beat the odds in Physics with solid concepts, and clinch their rank with smart Maths problem-solving. If you’re heading towards your first or tenth JEE attempt, remember: it’s not about picking just one favorite. It’s about knowing what each subject gifts you, and playing to those strengths for your best shot at the IIT dream.
