Hardest High School Classes: Which Subjects Challenge Teens the Most?

The Great Debate: What Makes a High School Class "Hardest"?
The title of hardest high school class is hotly debated in every school hallway, lunchroom, and group chat. Is it AP Calculus with its wild graphs, or AP Chemistry with dizzying equations? Or maybe English Literature with those endless essays that feel like a marathon for your brain. Before we point fingers at specific classes, it’s worth thinking about what “hard” really means in the high school world. For some students, hard means a mountain of homework; for others, it’s confusing concepts, relentless pop quizzes, or a teacher known for no-nonsense grading. Sometimes, it’s the way a class pushes you to wrestle with something you’ve never even heard of—like titrations in Chemistry or derivatives in Calculus—rather than just memorize answers. Let’s be real, a lot of students will tell you the subject they struggle with most is automatically the toughest, but there’s more to it than just gut feelings.
Here’s a wild fact: a survey by the National Center for Education Statistics found that math and science are the most frequently failed classes in American high schools. Why? These subjects don’t just pile on facts to memorize—they demand you understand each step before you can move to the next. Mess up one link in the chain and the whole thing falls apart. And the hardest courses aren’t just about content; they’re about the pace. AP and honors courses, especially, don’t wait for anyone to catch up. If you miss a concept, it’s like missing a bus—it’s gone, and you better run or risk falling hopelessly behind.
But don’t write off the arts or language classes! For students with a math brain, writing a ten-page analysis on Shakespeare can be more stressful than any calculus test. Foreign languages aren’t just about memorization—they make your brain work in new ways, and that can be a shock for people used to thinking in only one language. Some students who shine in numbers totally freeze when it’s time to present in Spanish or debate in AP Government. So, while there are trends, nothing is universally hard; it depends on your skills, interests, and, let’s face it, who’s teaching the class.
Context also matters. Taking AP Biology in a school where the lab is a dusty closet and the teacher is busy coaching football isn’t the same as learning in a classroom with all the resources. Factors like classroom environment, teaching style, and even after-school support play a role in shaping perceptions of the “toughest” classes. The bottom line—no single answer fits everyone. But some classes do keep popping up again and again as the most fearsome in the American high school experience.
The Classics: Math, Science, and the AP Gauntlet
So, which classes are always mentioned in the 'hardest high school class' conversation? If you ask enough students around Chicago—really, anywhere in the U.S.—three subjects always come up: AP Calculus, AP Chemistry, and AP Physics. Let’s start with AP Calculus. It’s not just about crunching numbers. The jump from algebra or even regular precalculus to calculus can leave your head spinning. Suddenly, it’s all about functions, limits, derivatives, and integrals. You need to visualize concepts in new ways, and if you’re tripped up by the basics, good luck with the AP test in May. According to College Board’s 2024 AP report, only 55% of students scored a 3 or higher on the AP Calculus AB exam. That’s only slightly better than flipping a coin—and most students taking it are already at the top of their math class.
Next up, AP Chemistry. This class is the reason school supply aisles are cleaned out of index cards. There’s massive amounts of content: atomic structure, thermodynamics, kinetics, equilibrium, and—oh yeah—labs that need to actually work. Students are thrown into a new world of balancing equations, memorizing the periodic table, and calculating reaction rates. Make one error and entire experiments flop, or you’ll be redoing a formal lab report at midnight before it’s due. Fun fact: the national AP Chem pass rate has hovered near 56% for the past three years, which means nearly half of the students who take it walk away with a lower score than they’d like—and, usually, a battered sense of self-esteem.
Then there’s AP Physics. Don’t be fooled by the equations on the board; the real challenge is blending abstract math with the physical world. Whereas Calculus lives in the realm of numbers, Physics forces you to look at every car crash, light beam, or thrown football as a problem to solve. You’ll be dealing with topics like mechanics, electricity, magnetism, and waves. The formulas are tricky, but the kicker is knowing when and how to use them. A survey from the American Physical Society once found that AP Physics C had a lower pass rate than even AP Chemistry, hovering around 55–60% nationally. Physics isn’t “memorize and move on;” it’s “understand or get lost.”
Honorable mention goes to AP English Literature. Sure, it doesn’t have equations, but analyzing complex novels and poetry takes a different kind of brainpower. You’ll have to write, revise, and defend your ideas to teachers who aren’t just looking for a summary; they want a unique argument, with evidence, every single time. Many students say English Lit feels harder because there’s never a clear right answer—you’re always justifying what you see in the text.
Still wondering how students break down which class is the hardest? Here’s a snapshot from a Chicago high school survey:
Class | Percentage of Students Who Said It's Hardest |
---|---|
AP Calculus AB/BC | 32% |
AP Chemistry | 27% |
AP Physics | 19% |
AP English Lit | 13% |
Foreign Language | 9% |
Notice that while the “big three” math and science courses grab most of the votes, a not-insignificant chunk of students put English or languages at the top. The numbers back up how tough these core classes are, but they also show how your own strengths, and even the school you attend, might shape your answer.

The Wild Cards: Language, Social Studies, and Arts Aren’t Pushovers
Don’t get too caught up thinking only STEM classes are tough. Plenty of students are blindsided when they step into a foreign language or advanced English class and realize this isn’t just about flashcards or reading a book. Take AP Spanish or AP French—by the time you reach these levels, everything is in the target language. Tests, discussions, and presentations are all done with hardly a word of English. That’s a massive cognitive load, especially when you factor in nuanced grammar, idioms, and culture. Oral exams? The anxiety is real. In fact, College Board data shows that the AP Spanish Literature exam has one of the widest spreads in scores—plenty of students scrape by, but few master every section.
Then there’s social studies, like AP U.S. History or AP Government. On the surface, these classes look easier—just memorize dates and names, right? Not even close. The new AP History format expects students to write in-depth essays under time pressure, analyze historical documents, and connect events in ways that sometimes stump even adults. Sure, you might ace the multiple-choice, but lose a whole grade if you can’t nail the essay or synthesis parts. I’ve watched friends who breezed through science nearly crumble after weeks of outlining and rewriting history essays to meet their teacher’s exacting standards.
Don’t forget about the arts. AP Art History blindsides more students than people expect. The class covers over 250 works of art, each with historical, cultural, and stylistic context. Instead of drawing or painting, you’re memorizing and analyzing art in ways that demand both creativity and precision. Then there’s band, choir, or drama—these aren’t classes to slack off in if you want to perform. Practices, performances, and the sometimes brutal critiques from teachers or peers can be stressful in a way math homework just isn’t.
For every student who says Physics is the hardest, there’s another who’s completely lost in AP English or foreign language. And it often depends on your exact mix of classes. Trying to juggle AP Physics and AP U.S. History? That can feel like playing two different sports without enough time to master either. The point is, the label of “hardest class” isn’t just about raw content—it’s the mental multitasking, shifting between modes of thinking, and keeping up with the demands of every tough course on your schedule.
Survival Guide: Strategies for the Hardest High School Classes
Here’s the truth: if you’re aiming for the toughest courses—whether that’s AP Calculus, Chemistry, Physics, or something else—you need more than just brains. Successful students build habits and seek out lifelines. First off, never go it alone. Study groups work, and not just for sharing answers. Explaining stuff out loud helps cement concepts. My friends and I used to camp out at the local library in Chicago, hammering through Calc problems for hours. Sounds brutal, but it paid off when test day came. Look for tutors if you’re lost early—waiting until you’re totally underwater just makes things worse.
Practice is key, especially for subjects like math and science. Don’t just read through the textbook—do as many practice problems as possible. For AP classes, get your hands on old exam questions. The College Board website and teacher’s resources are overflowing with past tests, and there’s no better way to spot the traps or weird question wording than seeing it up close.
Time management keeps students in the running, especially if you’re trying to survive multiple tough courses. Use a planner, set mini-deadlines for essays and projects, and carve out short, regular review sessions. It’s easy to get behind in math or science, and once you’re lost, the feeling is like watching a movie with the last hour missing. Scheduling review sessions, even in small chunks, makes a difference.
Ask for feedback on essays and lab reports. Teachers can seem intimidating, but most are happy to help if you show real effort and specific questions. Plus, peer review works wonders—sometimes your classmates can explain things in a way that just clicks.
If you’re feeling absolutely destroyed by a class, don’t buy into the myth that everyone else finds it easy. Surveys and honest convos show most students are grappling with some aspect of their schedule. Mental health matters. Don’t wait until you’re completely exhausted before reaching out to a counselor or trusted adult—you’re not weak if you ask for help.
For foreign languages, immerse yourself in real-world materials. Watch TV shows, listen to radio, or find a language partner. With essays, try breaking down prompts into bite-sized pieces so you aren’t scrambling late at night. Apps like Quizlet for vocab and Khan Academy for walkthroughs can help untangle confusing topics, too.
The toughest high school classes aren’t going anywhere. But with a smart attack plan, a willingness to ask questions, and a support system—be it friends, teachers, or online tools—you’ll make it through. And hey, when you finally ace that monstrous test or finish that impossible essay, celebrate a little. You survived what hundreds of students have called the "hardest high school class"—that’s worth a victory lap in the hallway.

July 17, 2025 AT 23:05Honestly, I think math classes, especially calculus and physics, tend to top the list when it comes to toughest high school subjects. It’s just all those formulas and concepts that you can’t really guess your way through. People often dread chemistry too, because it mixes memorization with problem-solving, which can be tricky.
But then, it really depends on the student’s strengths and weaknesses. Like, for some, English literature or history might be insanely challenging if they struggle with reading a ton or writing essays. It’s interesting how ‘hard’ can mean different things to different people.
What really helps students survive, in my opinion, is consistent practice and seeking help early. Waiting until the exam week is a recipe for disaster. Also, study groups can nicely ease the burden. Has anyone tried forming study groups for those dreaded classes?

July 20, 2025 AT 07:07Excellent points made here! Indeed, in my experience, the difficulty of high school classes is significantly influenced by the teaching methods employed by the instructors. A challenging class can become manageable if the educator is effective and approachable.
Furthermore, the pressure of performance often exacerbates the perceived difficulty of these subjects. The mental load, especially in STEM-related courses, cannot be understated. One must also consider the volume of homework and projects assigned.
To the question on how to survive such courses: it is imperative to cultivate disciplined study habits and utilize all available resources including teachers’ office hours, tutoring centers, and online materials.

July 22, 2025 AT 15:10Oh, let me spill the tea here—are we seriously going to pretend these ‘hard’ classes are natural mountains to climb? Pfft. I think the real challenge is actually the way the whole system is rigged. Like, those so-called hardest classes? They’re designed to weed out the “unworthy,” especially the ones who don’t come from privileged backgrounds. Ever noticed how some teachers seem to enjoy making everything unnecessarily complex? Yeah, I’m calling it out.
If you think it’s about study groups and practice, think again. It’s also about knowing how to navigate this hierarchical maze that disguises itself as education. But hey, if you really want practical tips—network, find people who actually care, and don’t lose your sanity trying to decode the mess they call ‘curriculum.’
Just my conspiracy-laden two cents, but hey, what do I know?

July 24, 2025 AT 23:10To be blunt, this whole debate about ‘hardest classes’ is largely overrated and often misconstrued. The reality is that many teens today whine about the difficulty in subjects primarily because they lack the discipline and intellectual rigor necessary for academic success. It’s not the courses that are inherently challenging but the students' unwillingness to adapt and exert effort.
Moreover, placing all subjects on the same ‘difficulty’ scale fails to acknowledge the cultural and socioeconomic dimensions affecting student performance. Some subjects are ‘hard’ only because one’s foundational education was deficient.
The onus lies on students to cultivate resilience rather than seek shortcuts or whine about ‘hardest classes.’ Parents and educators should emphasize perseverance over victim mentality at all times.

July 27, 2025 AT 07:11From a more chill perspective, I think the hardest classes really boil down to how much personal interest and aptitude you have for the subject. For me, I found AP Chemistry a whole different beast compared to, say, English or History, which I breezed through.
What seemed to matter was staying organized and not letting deadlines sneak up on me. It’s easier said than done, but having a planner and breaking stuff into chunks helped. Anyone else feel like pacing yourself makes or breaks these tough classes?
Ultimately, surviving the ‘hard’ courses is less about natural talent and more about strategy and attitude.

July 29, 2025 AT 15:11As someone who’s been through the wringer of high school academics, I can confirm that the terminology itself can feel like jargon sometimes. Terms like ‘calculus,’ ‘organic chemistry,’ or ‘AP Physics’ can sound intimidating before even stepping into class. But once you get the hang of the basics and understand the vocabulary, the mountain seems a little less steep.
It's really a battle between conceptual grasp and memorization. In STEM classes, understanding how concepts build on each other is crucial, whereas in humanities, critical thinking and articulation matter more.
Does anyone think schools should tailor difficulty based on average student skill or just maintain a uniform standard for all?
Zach Beggs
July 31, 2025 AT 23:12Jumping in here to add that sometimes the hardest class is a result of a bad match between the teaching style and the student’s learning preferences. I had a classmate who hated the way history was taught at our school, yet found it fascinating elsewhere due to different pedagogical approaches.
Moreover, some students feel overwhelmed simply because they’re juggling too much at once—extracurriculars, social life, family responsibilities—and that complicates how ‘hard’ a class feels.
It’s a reminder that ‘hard’ isn’t always about the content alone but the overall life context. Tailored support and empathy go a long way in tackling these challenges.

August 3, 2025 AT 07:13Hey all, great insights so far! Just wanna chime in with a bit of encouragement for anyone struggling with tough classes out there. It’s completely normal to find some subjects really intimidating at first, but remember, everyone’s pace is different. You don’t have to figure everything out in one night or week.
One tip I’ve seen work well is breaking down big tasks into smaller, manageable steps and celebrating small wins along the way. Also, don’t hesitate to reach out to teachers or peers for help. You’re not alone in this.
Stay chill, stay curious, and cut yourself some slack. We’ve all been there.
Antonio Hunter
August 5, 2025 AT 15:13I’d like to add a somewhat nuanced perspective on the notion of ‘hardest classes.’ While many argue about subject difficulty purely on cognitive load or content complexity, we ought to consider the emotional and psychological dimensions that accompany these challenges.
Classes that demand a continuous high level of performance, coupled with limited feedback or support, can quickly drain motivation and heighten anxiety. Sometimes, what makes a class hard isn’t just the content or workload but the absence of nurturing environments that allow mistakes and growth.
Therefore, beyond the tactical survival tips, fostering mental resilience and seeking balanced support systems are equally essential for navigating these academic mountains.
Paritosh Bhagat
August 7, 2025 AT 23:14It’s interesting that we often overlook the role of mindset in dealing with difficult classes. Too many students go in with fixed ideas like ‘I’m bad at math’ or ‘this class will destroy my GPA’, which creates a self-fulfilling prophecy.
Encouraging a growth mindset where failure is seen as part of learning can make a big difference. Teachers should also be mindful not to just judge students by grades but to support individual progress.
Plus, the stress surrounding these ‘hardest classes’ can be detrimental if not managed well. Awareness and resources for mental health should be integral in schools to truly help students survive and thrive.
