Inside MIT: Course Numbers, UROP, Hacks, and the East-vs-West Campus Culture

Inside MIT: Course Numbers, UROP, Hacks, and the East-vs-West Campus Culture

Most universities can be described in a paragraph or two. MIT cannot. From the moment you arrive in Cambridge, Massachusetts, you encounter an institution with its own vocabulary, its own calendar, its own dorm cultures, and its own sense of humor. Students do not say "I'm majoring in computer science" — they say "I'm a Course 6." Freshmen take their entire fall semester pass/no-record. Every few years, someone wakes up to find a police car balanced on top of the Great Dome.

If you are an international student considering MIT, or just curious about what life at one of the world's most selective technical universities looks like, this guide walks through the quirks, traditions, and daily realities of being an MIT undergraduate in 2026.

Everything Is a Number: The Course System

MIT does not call majors "majors." It calls them "Courses," and assigns each a number. The numbering reflects the order in which departments were founded, which means the numbers are essentially random to anyone who does not already know them. Students self-identify by Course number — meet someone in a dining hall and they will tell you, "I'm a Course 6" or "I'm double-majoring in 18 and 8."

Here is a quick guide to the Courses you will hear about most often:

  • Course 1: Civil and Environmental Engineering
  • Course 2: Mechanical Engineering — very popular, with a strong hands-on culture
  • Course 3: Materials Science and Engineering
  • Course 6: Electrical Engineering and Computer Science (EECS) — the flagship, drawing roughly 40 percent of undergrads
  • Course 8: Physics
  • Course 9: Brain and Cognitive Sciences
  • Course 10: Chemical Engineering
  • Course 14: Economics
  • Course 15: Sloan School of Management (undergraduates major in Management Science)
  • Course 16: Aeronautics and Astronautics
  • Course 18: Mathematics — famously rigorous, feeding directly into top PhD programs
  • Course 21: Humanities
  • Course 22: Nuclear Science and Engineering
  • Course 24: Linguistics and Philosophy

Course 6 has so many tracks that it has its own sub-numbering system: 6-1 (Electrical Engineering), 6-2 (EE and CS hybrid), 6-3 (Computer Science), 6-7 (CS and Molecular Biology), 6-9 (Computation and Cognition), and 6-14 (CS, Economics, and Data Science). If you overhear a conversation about "6-14 versus 14" or "switching from 6-2 to 6-3," you are listening to MIT students deciding their futures using a code that takes a week to learn and a lifetime to stop using.

The General Institute Requirements (GIRs)

Before diving into their Course, students clear a set of shared foundational requirements called the General Institute Requirements, or GIRs. Every undergraduate, regardless of major, completes the same core:

  • Six Science Core classes: two semesters of calculus, two semesters of physics, one chemistry, and one biology — non-negotiable, and part of why MIT graduates share a technical language across disciplines.
  • Eight HASS courses in Humanities, Arts, and Social Sciences, including a HASS Concentration — three courses in one area that push you beyond the introductory level.
  • Two Restricted Electives in Science and Technology (REST) — advanced technical courses outside your major.
  • Two lab requirements.
  • Communication-Intensive classes: CI-H (communication-intensive humanities) and CI-M (communication-intensive in your major), ensuring that even engineers graduate having written and presented substantial work.
  • Physical education and a swim test. Yes, MIT really does require you to pass a swim test to graduate.

The GIRs occupy a significant chunk of the first two years, but they are also why MIT graduates describe themselves as "technical generalists." A Course 22 student has taken real biology. A Course 21 humanities student has taken calculus and physics alongside their literature seminars.

First-Term P/NR: The Gentlest Welcome in American Higher Education

One of MIT's most distinctive policies is Pass / No Record (P/NR) for the entire fall semester of freshman year:

  • If you pass, your transcript shows a "P." There is no letter grade and no GPA impact.
  • If you do not pass, the class simply does not appear on your transcript at all.

The design intent is straightforward: MIT knows its workload takes adjustment, and that international students navigating a new country, language, and academic system need room to recalibrate without a permanent mark. P/NR encourages exploration, reduces burnout, and gives students permission to take a hard class outside their comfort zone.

In the spring of freshman year, the training wheels come partially off. Grades default to ABC/No Record — you can earn A, B, or C, but D's and F's still do not appear. By sophomore year, the full grading scale applies.

UROP: Research From Day One

The Undergraduate Research Opportunities Program, or UROP, is one of MIT's defining features. Founded in 1969, UROP pioneered undergraduate research in the United States and has served as a model for similar programs worldwide.

The numbers tell the story: more than 90 percent of MIT undergraduates do at least one UROP before graduating. UROPs are real research, not busywork. You work directly with faculty and graduate students on active projects, for credit or pay during the academic year and paid in the summer.

The application process is refreshingly informal. You identify labs whose work interests you by browsing department websites and papers, then email the professor or a graduate student directly. A short, specific email that shows you have read their work tends to get responses. You do not need prior research experience, and many undergraduates start their first UROP during freshman year.

For international students considering graduate school, startups, or research-oriented industry careers, UROP can be foundational — where you develop the skills, references, and track record that top labs and graduate admissions committees look for.

East Campus vs West Campus: The Dorm Divide

MIT's residential system has a genuine cultural split that shapes campus life. Dorms are not interchangeable — each has its own personality, traditions, and reputation, and incoming freshmen rank dorms after acceptance.

East Campus: Eclectic, Counter-Culture, Hands-On

The East side is the traditional home of MIT's hacker, maker, and builder communities, attracting students who want a space that feels customized, experimental, and a little weird.

  • East Campus dorm itself is the spiritual center: hackers, theater geeks, students who build elaborate lofts and repaint their halls every year.
  • Random Hall is smaller and famously social, organized around its kitchens, with each floor running its own culture and naming tradition.
  • Senior House closed in 2018, but its legacy is still part of how students talk about East Campus identity.
  • Bexley Hall has been closed for renovation for years; older students still reference its small alternative-scene reputation.

West Campus: Mainstream, Athletic, Traditional

The West side leans toward a more conventional dorm experience — larger buildings, more athletes, more mainstream social rhythms.

  • Burton-Conner: social, organized around double rooms and communal kitchens.
  • Baker House: traditional, social, heavily athletic.
  • MacGregor: quiet, mostly single rooms, suite-style living.
  • McCormick: women-only.
  • New House: international and music-oriented, with language-themed entries.
  • Maseeh: large and modern.
  • Simmons: known for its sponge-like architecture and modern amenities.
  • Next House: large, with varied sub-cultures inside.

The East-vs-West framing oversimplifies a real spectrum, but it is a framing students use themselves. Where you live at MIT strongly affects who your friends are and what daily life looks like, which is why the dorm ranking process gets surprisingly intense.

Hack Culture

"Hacks" at MIT are not what the word means elsewhere. They are not computer break-ins and they are not ordinary dorm pranks. MIT hacks are elaborate, anonymous, technically impressive stunts combining engineering skill with a specific ethical code.

Famous hacks are lovingly documented:

  • A working Campus Police car balanced on top of the Great Dome in 1994.
  • A life-size R2-D2 appearing on the dome during a Star Wars release.
  • An MIT building facade transformed into a playable game of Tetris.
  • The legendary theft (and eventual return) of Caltech's 1.7-ton cannon.

Hacks follow an unwritten ethics code: no damage, no permanent alterations, the hack must be undoable (often by the hackers themselves, who quietly restore everything), nothing offensive, and elegance matters — the cleverer the engineering, the better the hack.

Hacks are usually executed at night and anonymously. Many are archived at hacks.mit.edu, which is worth browsing. Part of what makes MIT feel distinctive is that the administration tolerates — and, within limits, quietly respects — this tradition.

Drinking From the Firehose

One of MIT's oldest self-descriptions is that an education there feels like "drinking from a firehose." It captures something real: the pace can be intense, problem sets are demanding, and the cultural expectation is that you will be stretched.

That said, it is worth pushing back on the myth that every MIT student is constantly overwhelmed. Reality varies enormously by major, term, and how someone manages their time. Some semesters feel manageable; some are brutal. Students who budget time, collaborate on psets, and pick extracurriculars deliberately generally do well.

"Pset" culture — short for problem set — is central. Most technical classes assign weekly psets, and collaboration is actively encouraged within rules each class specifies. Study groups form in dorms, lounges, libraries, and around whiteboards. Academic integrity is taken seriously and cheating is punished severely, but the line between legitimate collaboration and violation is well-defined and clearly taught.

IAP: The January Term

Between the fall and spring semesters, MIT runs a four-week mini-term called the Independent Activities Period, or IAP. Founded in 1971, IAP is highly flexible and almost entirely optional.

During IAP, students can take short courses in everything from machine learning workshops to cooking, glassblowing, knitting, or languages. They can do research, compete in robotics, take internships, travel abroad on MIT programs, or simply rest. IAP classes are typically pass/fail or ungraded, keeping the low-stakes exploratory spirit intact. Some of MIT's most memorable experiences happen in IAP — the project built with friends in a lab for three weeks, the language intensive that finally clicked, the robotics competition that cemented a career direction.

Course Load and Difficulty

A typical MIT class is measured in "units," with most worth 12 units — roughly one unit per hour of weekly work, so about 12 hours each. The typical term load is four to five classes; some students regularly take six or more.

Difficulty varies significantly by department and class. Course 18 upper-level mathematics is notoriously rigorous, and certain Course 6 classes have reputations that precede them. But it would be inaccurate to describe every MIT class as crushingly hard. Many are well-designed, well-taught, and genuinely enjoyable. The "MIT mentality" is partly self-fulfilling — students arrive expecting to handle difficulty, and they often do.

Athletics, Clubs, and Maker Communities

MIT competes in NCAA Division III, with more than 30 varsity teams and a similar number of club sports. The Charles River gives rowing, sailing, and crew a visible presence on campus, and fencing, cross-country, and sailing are historically strong programs. Intramural sports are widely played, with leagues running everything from soccer to inner-tube water polo.

Beyond traditional athletics, MIT's maker communities are unusual in scale and accessibility — the Edgerton Center runs hands-on programs and lab spaces, the Glass Lab teaches glassblowing, the Hobby Shop is a fully equipped wood and metal shop, and MITERS (the student-run electronics shop) is where students build everything from custom CNC machines to electric vehicles.

Approximately 30 percent of undergraduates participate in Greek life, with 26 fraternities, 6 sororities, and 6 Independent Living Groups. MIT Greek life tends to be more academically focused than stereotypical depictions of American Greek systems, though variation is wide.

The Humanities Side

One of the things that surprises students at MIT is how seriously the humanities are taken. The HASS requirements are not throwaway electives. Classes like 21W.730 (writing), 21M.030 (music history), and 21H.301 (history) are taught by working scholars and are often genuinely demanding. The HASS Concentration pushes students to develop real depth in one humanities area, and many MIT graduates describe their HASS classes as some of the most formative experiences of their education. It is not unusual for a Course 6 student to name a writing seminar or philosophy course as their favorite class.

Career Outcomes

MIT graduates are recruited heavily by tech companies, finance firms, consulting firms, and graduate programs. Median starting salaries for undergraduates typically fall in the range of roughly 95,000 to 110,000 US dollars, though outcomes vary widely by major and role. Top employers include Google, Microsoft, Meta, Apple, SpaceX, Citadel, Jane Street, Two Sigma, and McKinsey.

The startup pipeline is strong, and the on-campus ecosystem — MIT's venture network, the Sandbox Innovation Fund, the Martin Trust Center — supports student founders directly. Graduate school placement is strong across fields, particularly in engineering, computer science, mathematics, and the sciences. None of this is a guarantee. Career outcomes depend on what you actually do at MIT, but the opportunities are there in ways that are unusual even by the standards of selective US universities.

The Boston and Cambridge Environment

MIT sits in Cambridge, Massachusetts, a historic, walkable city packed with bookstores, cafes, and academic institutions. Harvard is a short walk up Massachusetts Avenue. Cross the Charles River and you are in Boston, a city with dozens of universities, world-class museums, professional sports teams, and a dense restaurant scene. The Red Line subway connects MIT directly to Harvard Square in one direction and downtown Boston in the other.

The climate is a genuine four-season experience. Winters are cold and can include significant snow; falls are famously beautiful; summers are warm and humid. If you are coming from a warm climate, budget for real winter clothing.

What Surprises International Students Most

A few things catch international students off guard at MIT:

  • The workload is real. The firehose metaphor is not marketing. You will need to develop time management skills you may not have needed before.
  • Collaboration is the norm. The stereotype of isolated geniuses working alone is almost the opposite of how MIT functions. Pset groups, study partners, and collaborative projects are central. Academic integrity rules are clearly drawn and strictly enforced, but within those rules, working together is encouraged.
  • Professor accessibility. MIT faculty, including Nobel laureates, teach undergraduates and hold office hours. Students regularly have real conversations with people whose textbooks they have read.
  • Hack culture is real. You will almost certainly see at least one hack during your time at MIT.
  • The institute has a deep weirdness. MIT has a sense of humor about itself, a love of tradition, and a tolerance for eccentricity rare in universities of its stature. Embracing that culture is part of what makes MIT work.

MIT is not the right university for everyone. The pace is demanding, the culture is specific, and the workload is real. But for students who want to live somewhere that takes technical work seriously, treats undergraduates as researchers from day one, and balances rigor with genuine humor and community, MIT is a remarkable place.
