Ever heard whispers in the corridor about someone flunking math or history wrecking someone's summer? You know the scene—faces buried in textbooks, parents doing daily rounds of 'Have you studied enough?' The drama about the toughest subject in CBSE isn’t new. It splits families at the dinner table, sparks cold wars among friends, and keeps coaching centers in business. What's really the hardest subject in CBSE, though? Is it that infamous CBSE math paper with the ‘unexpected twist’, or maybe physics with all its laws and formulas? The answer isn’t what you usually hear. Let’s break it down, pull in facts, and talk about what makes CBSE a jungle for some and a walk in the park for others.
Battle of the Beasts: A Subject-by-Subject Reality Check
So, if you ask a group of students, you'll hear 'Math is evil!' from one corner and 'Biology is just cramming' from another. But the Central Board of Secondary Education (CBSE) isn't out to make students miserable. It tries to balance scoring high and learning something. But still, the perception of which is the toughest subject keeps changing year after year, and for good reason.
Physics, for instance, is often branded the ‘mind-twister’. The 2021 board exam saw over 58% of students say physics was tougher because—even if you mug up every chapter—application questions can knock you out cold. A question on the Doppler effect or a numerical on kinematics can eat minutes off the clock, fast! It’s the blend of concepts, mathematics, and logic that makes physics a recurring nightmare for many.
On the other hand, math has a bad rep too, thanks to its ruthless precision. There’s no ‘almost correct’ here. Data from a recent CBSE evaluation report (2022) showed, out of all major subjects, math had the lowest average score—67 out of 100. Miss a step, copy a formula wrong, or botch a sign? That’s it, marks gone. The anxiety spills over to even the brightest. Many toppers claim they spend double the time on math compared to any language or social science paper. But here’s the twist—math rewards effort. You might stumble a hundred times, but with practice, most tricky problems lose their scare.
What about chemistry? People say it strikes a fine balance—part memory game, part logic puzzle. But organic chemistry gets a special mention for turning chemistry from 'manageable' to mayhem. Visualizing molecules, memorizing reactions, not messing up experiments—it's all there. But it's not hellish; in fact, many CBSE students find chemistry the most ‘scoring’ among sciences once you crack the pattern. A key stat: in 2024, the chemistry average shot past 75 marks in several regions because most questions stuck to NCERT textbooks. That’s a massive hint—CBSE loves its prescribed material.
Now, the supposed ‘easier’ side—English, Hindi, or any language paper. These seem chill at first, but grades often slip on subjective answers. Miss out on the author’s intent, overlook a reference, or make grammar mistakes, and your scores take a hit. There’s little room for ‘rote’ learning here—it’s about articulation, understanding, and expressing ideas clearly. Even the 2023 CBSE toppers’ interviews reveal: ‘Don’t underestimate English! It’s trickier than you think.’
But for students in the humanities, history and geography have their own hurdles. History is notorious for its endless facts, dates, and causes. Geography drowns you in maps and endless data—rivers, resources, population charts. In a survey across five major schools in Delhi NCR, Class 10 students tagged geography maps as the ‘most feared’ oral exam. There’s nowhere to hide if you forget names or draw boundaries incorrectly.
Subject | Avg. Marks (2024) | Students Tagging as Toughest (%) |
---|---|---|
Math | 67 | 41% |
Physics | 69 | 28% |
Chemistry | 75 | 16% |
Biology | 76 | 7% |
English | 79 | 6% |
History | 73 | 2% |
So, the answer isn’t straightforward. Each subject has its own devil. Scientific types groan about math and physics, the memory champions curse history, and those who struggle with words quietly battle it out in English. In CBSE, the ‘toughest’ tag depends on your strengths, interests, and sometimes, sheer luck on exam day.

Myths, Facts, and Teacher Tales: What Makes a Subject Difficult?
Here’s something wild—most students fixate on what seniors or teachers say, ‘Physics is only for geniuses!’ or ‘Math is a paper you can’t ace without coaching!’ But the real challenge often has little to do with the subject itself. It’s who teaches it. Remember Mrs. Ahuja’s physics lectures where even Newton’s laws felt like bedtime stories? Compare that to Mr. Singh, who made math seem like hieroglyphics. A CBSE poll in 2023 found that students in schools with interactive, engaging teachers scored up to 14% higher in the same ‘tough’ subjects versus rote, textbook-heavy classes.
Let’s talk about the other big myth—‘last-minute cramming works for everything’. Try that with math or physics, and you’ll see instant regret. These subjects punish you for lack of practice. You need muscle memory for equations and stamina for problem-solving. Same logic applies to chemistry’s organic reactions—you need to recall mechanisms fast, not stare at the wall hoping memory will bail you out. But for subjects like history or political science, some manage to scrape through with marathon revision on exam night. But again, pattern-recognition helps more than pure mugging. The CBSE has started sneaking higher-order thinking questions even in the humanities. Those aren’t forgiving if you just rote-learn paragraphs.
There’s also the little-discussed effect of sample papers and marking schemes. Did you know that the board makes its marking quite transparent? Annual teacher workshops reveal that math and science evaluations have clear stepwise marking, so you can score even for attempting parts of a sum. Essay-type answers in Humanities and English, however, depend heavily on presentation, coherence, and hitting key points. An answer with poor structure, even if correct, loses marks. The path to scoring isn’t always about having all answers memorized—it’s about knowing what the board wants to see.
And what about peer influence? Every batch has that popular student who declares a subject 'impossible', scaring the rest. This pressure is real. Social studies (SST) used to wear the 'easy' cap for years. But when CBSE introduced map-based application questions, complaints shot up online. Students suddenly realized, memorization alone isn’t enough if you can’t apply concepts in context. Physics and math get called out most because failure here feels toughest to fix—but history and even English have seen their share of tears.
Sometimes what feels difficult comes down to board patterns too. CBSE occasionally throws a curveball, like the notorious Class 12 Math 2015 paper that left students weeping, or unexpected application-based biology questions where diagrams suddenly mattered for half the marks. Social media gets flooded after every such exam—a Twitter search on CBSE math after exam day will show memes, complaints, success stories, and even petitions. The infamous 2019 physics paper, for example, was trending for two days after kids called questions "out of syllabus" even though they were just reworded familiar problems.
Let’s get real—difficulty is as much about mindset and comfort with a subject as it is about what’s on paper. A student who's done weekly self-testing in history will laugh off a tricky chapter. Someone who’s spent two months practising calculus will hardly flinch at integrals. The subject’s ‘toughness’ is never fixed universally. It beats to your own rhythm, your prep style, and yes, sometimes just plain luck with the questions on the day.

Tips and Survival Hacks: Turning the ‘Toughest Subject’ Into a Scoring One
Stuck staring at a biology chart that looks like alien hieroglyphs? Arithmetic making you sweat at 2 a.m.? You’re not the only one. But here’s a bit of sanity—every so-called tough subject has cracked some toppers’ codebooks, and you don’t need a magic wand to break in. Let’s get hands-on with some hacks that have saved countless CBSE survivors.
- Nail the NCERT First: This isn’t another cliché—it’s a life-saver. 89% of questions in math, science, and even humanities are lifted straight from the NCERT books or at least their style. Don’t jump to reference books until you’ve squeezed every exercise dry from the prescribed text.
- Sample Papers Aren’t a Gimmick: The CBSE board repeats question patterns—and sometimes entire questions—year after year. Multiple student analyses show scores jump by up to 19% just by solving the last 5 years’ papers and official sample sets.
- Plan Weekly Mock Tests: Consistency beats cramming every single time. Set aside one day a week for a full mock test under real exam conditions. Your time management, stamina, and accuracy will level up without you even realizing.
- Charts, Mind Maps, and Sticky Notes: For volatile subjects like organic chemistry reactions, history dates, biological diagrams—you want visuals in every corner of your room. Mind maps especially compress chapters into bite-sized visuals for a quick snapshot before the exam.
- Prep With Friends—But Only the Focused Ones: Group study sessions can spark those ‘aha!’ moments when someone cracks a tough equation or remembers a reaction you forgot. But pick your crew wisely—if the session turns to meme-sharing, you’re sunk.
- Teacher Clinics: Don’t be shy. Go ask teachers after class, or shoot them a message about the things you don’t get. Teachers quietly help the most determined. Data shows students who routinely clear their doubts with teachers are 31% more likely to score in the top percentile.
- Break the Monotony: If a subject starts to feel like torture, switch it up. Alternate tricky math problems with geography map work or short story practicing for English. Keeping the brain fresh does wonder for memory, retention, and mood.
- Leave No Weak Link: Don’t bet on ‘certain questions won’t appear’. Pupils who skip weak chapters hoping they won’t come up always pay for it. Examiner surveys show that random case-studies from usually-ignored chapters appear at least once in every board exam cycle.
- Daily Recaps: Make it a rule—15 minutes before bed, recap your toughest subject’s key points for the day. Brain studies prove that spaced repetition boosts retention by 40% over standard revision methods.
- Don’t Ignore Languages: Even if English or Hindi seem like ‘easy 90s’, a lot of CBSE students slip here because of overconfidence. Practice letter writing and comprehension passages. These sections are easy scores if you pay attention.
The best-kept secret? Teachers quietly admit the most ‘feared’ subject changes every year with the tough paper. But those who prepare smart—focused on the syllabus, steady revision, not ignoring basics—always manage to turn the hardest papers into their highest scores. Doesn’t matter if yours is math, physics, history, or English. It’s never about blind talent. It’s the grind, the right guidance, and not letting fear dictate your prep. The next time someone moans that a CBSE subject is ‘impossible’, just remember—every topper once felt the same way staring at their first practice paper. Stick with it and soon enough, impossible starts to feel boringly doable.
