r/mit on Reddit: First Semester Freshman Courses
April 8, 2019 -

Ever since being admitted to MIT, I have been lurking around various related message boards, and it seems there exists a common refrain that (due to the pass / no credit nature of first semester) one should not be afraid to take challenging classes and explore new things the first semester at MIT. This prospect is especially exciting to me, and I was wondering if there are any classes the good people of reddit deem to be extremely exciting / necessary / challenging to take freshman year.

For reference I am considering a major in mathematics (taken up to Complex Analysis) or biology (only formally taken AP Bio), and a minor in business, engineering, or CS (no real formal education in any of the three).

I am pretty flexible in what I want to take, and am really just looking to maximize the fun and knowledge gained in my freshman year. Any help would be greatly appreciated. :)

Edit: I don't want to come across as overconfident. I simply wish to utilize the first semester to learn my limits and see which subjects I am best in. Of course, I am keeping open the possibility of dropping courses.

I'm glad you're trying to challenge yourself. However, MIT is more difficult than high school (for the most part). The objective of pass/no record is to help you acclimatize to MIT. Don't take that for granted. You could try to take one challenging course freshman fall, but also be ready to drop it if it becomes too much.

Disclaimer: I'm assuming you either really want to challenge yourself and are willing to risk actually failing courses, or you're rather exceptional academically even among MIT students. So like, don't take this as advice, take it as information to have. I took a summer studying ahead and ASE'd out of most of the freshman classes and it was definitely worth doing. You get much more leeway to take interesting classes (and not die because grad classes are kind of insane) later on. As bad as freshman year is for some people, MIT only gets harder from there (and a lot harder by the time you get to capstone level classes). In math/CS: 18.200 or 6.042 (basically discrete math) are rather important to know for many subjects. But if you did math competitions and did very well, you can skip it. [EDIT: Apparently certain majors can't skip it and also, you'd have to substitute something more advanced anyways.] If you have the prerequisite (basically being able to do induction proofs very very fluently and creatively) 6.045 or 18.404 is the really interesting class, especially if you're interested in majoring in math; it's really easy for some people and really hard for others. 18.453 teaches about linear programming duality among other things and that is sort of a important concept for a lot of other things in math and CS. Also proof-heavy. You should probably know some linear algebra before taking it. In pure math: 18.100A or 18.100B (real analysis). If you're good at proofs, take 18.100B. It's an insanely hard introductory class (well, if Jerison is still teaching it) but it's taught super well and covers a bit of measure theory and functional analysis. Take 18.100P or Q if you want a CI-M very badly. Both versions are good intros to what kind of stuff modern math is built on. The 18.701/18.702 (abstract algebra) sequence is worth taking, too. If you've done real analysis already, 18.901 is cool. Exploring other majors: Maybe take a CI-H freshman fall because the essays eat up quite some time. In physics, I'd recommend 8.022. It's like a taste of theoretical physics from what I've heard. 8.033 was good too my year with Slatyer, but apparently the current prof calls things "trivial" way too much. In computer science, if you ase 6.0001 and take 6.009, you'll either love it or hate it. 6.006 and 6.046 are quite interesting. In music theory, 21M.301. 14.01 is really fun but is the opposite of a "challenge". All the "advanced" versions of freshman GIR classes are apparently good. I've never heard a bad thing about them.

r/mit on Reddit: Is course 18 alone enough?
September 30, 2025 -

It feels like everyone is doubling with 18 + something else. I am honestly only interested in math/stats, so 18 applied feels like the natural course. Not as interested in CS theory, so I don't think 18C is the right choice for me. It feels like no one is a single major in math, though, unless they want to go into academia? While I'm not sure what I want to do, I don't want to limit my options. Some things I have been considering are academia in operations research or applied math, quant trading/research (ew, I know), and data science.

r/mit on Reddit: I can't major in 20 if I don't take chemistry as a freshman?
December 20, 2018 -

I was planning my courseroad when I stumbled on Course XX's course flowchart: https://be.mit.edu/sites/default/files/documents/BESBFlowchart.pdf

I need to take 20.110 by sophomore year to graduate on time. 20.110 is only offered in the fall, which means I must take it by sophomore fall. But it has Chemistry (GIR) as a prereq, which means I must take Chemistry freshman spring (since I took 8.022 and 7.012 in the fall).

Is this really true? Are there really no Course 20s who got chemistry credit after freshman year?

Also, is it a better idea to take 5.111 over 3.091 if I want to go into 20? I've heard that 5.111 is very, very atomic-level, so I doubt I would be applying any of its principles as a bioengineer, but I just want to make sure.

March 15, 2024 -

Hey everyone! I'm a co2028 admit and I'm pretty deadset on attending mit, but have a couple of things I'm curious about before finally committing :)

I'm thinking about studying course 18, as i had a very heavy theoretical math bg throughout hs, but I'm also interested in exploring new pathways! areas I'm interested in include physics, architecture/design in general, and potentially aeroastro.

if any of y'all have personal experiences being singular about math in HS -> branching out at MIT -> ending back up in math, or alternatively, an entirely new subject area, I would love to hear your insight.

what aspects of the MIT experience make it conducive for this exploration? what aspects of it don't? any particular experiences with the pure math dept? i also get that there are options within course 18 itself, some of which are probably more "branched out" and flexible than others.

thanks so much guys, I'm so excited to hopefully be joining this community in the fall!!

Hey r/mit. I was wondering if anyone had any good class recommendations or suggestions on things to take this semester. I'm pretty open to any subject in any course number, as long as it's a good class.

For any alumni out there... any classes you wish you had taken / things that should absolutely not be missed?

Perhaps I misunderstood. ... I think it's a combination of a few things. Teaching not a priority for many professors (research is) and justifying the difficulty/fast pace with "mit students are smart they can figure it out".

r/mit on Reddit: What are the major differences between Course 20 and Course 7?
June 14, 2016 -

Yes, google and look at the curriculum.

However, there are a variety of differences between electives, i.e. what students are allowed to take and what they actually take.

Why do students chose one and not the other? Are there differences in "difficulty" (I hate this question too)?

Any insight appreciated

okay, this is something that I (once upon a time...) spent a lot of time thinking about. First -- biology and BE are both hard, but in different ways. In particular, the biology curriculum is designed so that you need to understand complex concepts and ideas at a very fundamental level. Exam questions often ask you to (A) look at some preliminary data and devise a hypothesis and then (B) design experiments that would prove said hypothesis. These exams are usually open book/open note, but just having those resources there won't help you -- you need to put in the effort to understand everything ahead of time and understand general approaches to problem solving in biology. If this sounds hard -- don't worry! The learning curve is relatively gentle, and the standard sophomore year classes are an excellent bridge to this sort of problem solving. I would characterize the BE department research-wise as having one large theme: can we apply engineering abstractions (as found in MechE, EECS, ChemE) to biological systems to enable molecular design? The answer is resoundingly yes and the way this trickles down into the curriculum is through an increased emphasis on modeling biological behavior (i.e. simulate a metabolic pathway numerically. what happens if you block this enzyme with a drug? etc) and on design of instrumentation (using knowledge from other fields) to study biological systems. Perhaps unsurprisingly, BE is more quantitative and mathematical than biology is, and has a lesser emphasis on the underlying science -- the department is more focused on, say, designing cool tools to enable biologists to learn new things rather than applying those tools themselves to learn new things. Not that there isn't science going on in the department, but it's certainly not the primary emphasis. I have some strong opinions about classes. Regardless of what path you take, I would highly encourage you to take: 7.05/5.07 (Biochemistry I) & 7.08/5.08 (Biochemistry II), 7.06 (Cell Biology), and 7.28 (Molecular Biology). If you really master these classes, there are so many doors in the life sciences that open as a result (even as an engineer). This is enough biology knowledge to be dangerous and let you attack a lot of novel problems.

It's the same essential difference as between Chemical Engineering and Chemistry. One focuses on applied knowledge, the other focuses on theoretical knowledge. Very roughly: Chemistry cares about finding new reactions. Can you make something new happen, once, on a lab bench? Chemical Engineering cares about making already-known reactions happen faster / cheaper / better. Can you take that new thing the Chemist found, and make it happen at a large scale in a production plant? Biology cares about the fundamental theory of biology. How does it all work? Can you deepen our knowledge of how it works? Course 7: https://biology.mit.edu/undergraduate/biology_mit_undergraduates Biological Engineering cares about applying engineering principals to biology. Given knowledge of how biology works, can you use that knowledge to solve a practical problem? Course 20: http://be.mit.edu/academic-programs/prospective-undergraduate

r/IAmA on Reddit: I spent the last 12 months learning MIT's 4-Year computer science curriculum, without taking classes. AMA
October 3, 2012 -

Someone linked to one of my videos here and there seemed to be some interest in an AMA, so here goes!

The best explanation of this weird experiment is my TEDx Talk. The talk was in May, before I had finished.


Basic story: I graduated with a business degree, but I really wanted to learn computer science. I wasn't keen on going back to school, and I didn't really need another undergrad degree, so I wanted to see whether it would be possible to learn the curriculum of MIT's famed CS program, without paying for tuition.

My goal was to pass the final exams and complete the programming projects for the classes in the degree. There's a lot more detail, but you can see an FAQ and access all the code/exams I wrote here.


Before I ruffle too many feathers of the hard working grads/CS majors, I'll answer a few common questions right off the bat:

  1. No, I didn't get a degree for this.

  2. I don't see my challenge as being == to the experience of getting a degree from MIT. But the course path I followed reasonably approximated the breadth of material, and using MITs actual final exams and programming projects provides a reasonable approximation to the evaluation methods.

  3. I worked on the project full-time, roughly 60 hours/week in the first few months, but shifting to 30-40 hours once I had completed a good chunk of the exams/classes.

I'll try to drop in to answer questions throughout the day.


Edit: Proof I am the person from the talks/videos: https://twitter.com/ScottHYoung/status/253504120445599745 (as for proof of having learned the material, the best I can offer is the code/exams I wrote, all uploaded here.)


Edit: Looks like the questions are winding down, and I need to get going. Thanks to everyone who participated, I hope I answered your question. If not, feel free to email me/check out my website: http://www.scotthyoung.com/blog/

Hi Scott! As someone who is thinking about doing something like you did I have some questions. Before I'm starting to ask you about your recent experience I want to make clear that I don't know anything about the education system in America (I live in the Netherlands) so I'm sorry if I ask some obvious/dumb questions.


  1. Why did you choose specific MIT to learn CS? Is it because MIT offers the only high-quality computer science study or is it because MIT offers the most online lectures? Or does it have another reason?

  2. Did you really needed ALL the online lectures of MIT? Is it possible to do something like you did even if the study isn’t providing all the lectures online?

  3. We all know that you needed a goal (learning MIT CS in 12 months), the material (books and online education) and a lot of self discipline. But was there anything else that you really needed in the past 12 months? What kept you through?

  4. How did you actually do it? Can you tell more about the timetable you used and how it worked out for you? Besides the timetable, did you use other 'things' to get the job done?

  5. You now have all the knowledge to get the degree, but you mentioned that you haven’t. Is that because MIT can’t give you the degree because you didn’t follow the lectures and pay the school money? Are there studies who can still give you the degree even if you don't follow any classes or paid school money?

  6. Do you think you still had a social life besides this project? What was the biggest downside to this experience?

  7. If you had a chance to do it again, what would you do differently?

  8. Because you’re now done (congratulations!) I want to ask if you have some allround tips/tricks to the people who will follow your path and do something alike. (Maybe not learning MIT CS, but for other studies as well).


Again: Congratulations man. I think you deserve a vacation :)
