Why does CS50 use C?
See this answer on Quora!
Can first years take both CS50 and a Freshman Seminar SAT/UNS?
Yes. Even though first years may not ordinarily enroll in both a Freshman Seminar and another non-letter-graded course in any one term, they may take both CS50 and a Freshman Seminar SAT/UNS.
Should first years take CS50?
Yes, if they would like! In Fall 2017, first years composed a majority of CS50’s student body. While students should be mindful of CS50’s workload and should perhaps avoid taking 4 pset-based classes, students shouldn’t shy away (from CS50 or any other introductory course) simply because they’re first years.
Does CS50 satisfy a Gen Ed requirement?
Yes. You may may take CS50 (SAT/UNS or for a letter grade) to fulfill the Science and Engineering and Applied Science distribution requirement or the Quantitative Reasoning with Data requirement, but not both.
How can I change from SAT/UNS to letter grade?
In my.harvard, select Student Home, then select Documents, and then, under Document Center, download Fall 2019- P/F Petition as a PDF. Indicate a change from SUS to LG, and drop off the form at the Registrar’s office in Suite 450 of the Smith Center (at 1350 Massachusetts Avenue) no later than 5pm on the term’s fifth Monday. (There is no fee from the Registrar for changing grading basis.) If you email (a scan or photo of) the form to firstname.lastname@example.org, one of the course’s heads can sign it digitally and email it back to you for your advisor’s and resident dean’s signatures.
If you are a GSAS student, submit this form. Even though it’s “for language courses only,” you may indeed use it for CS50.
If you are a grad student at another school, email email@example.com, and FAS’s Registrar will make the change for you.
Should I take CS50 SAT/UNS or for a letter grade?
Unless your (potential) concentration requires that you take CS50 for a letter grade, you should take CS50 SAT/UNS, which is the default. Not only does SAT/UNS allow you to explore an unfamiliar field (whether CS or some other) without fear of “failure,” odds are, more pragmatically, it will reduce undue stress during your semester’s busier times.
What is CS50’s grade distribution?
Per CS50’s syllabus, “what ultimately matters in this course is not so much where you end up relative to your classmates but where you, in Week 11, end up relative to yourself in Week 0.” Accordingly, provided you put in the time and effort, odds are you’ll fare quite well! In Fall 2018, 41% of students received a final grade of SAT, 30% of students received a final grade of A, 18% of students received a final grade of A-, 6% of students received a final grade in the B range, and 2% of students received a final grade in the C range, per the below. In cases of E (<1%) or UNS (1%) were typically extenuating circumstances.
Which concentrations offer concentration credit for CS50?
See this spreadsheet.
Which concentrations require a letter grade in order for CS50 to count for concentration credit?
See this spreadsheet. Note that you may take CS50 SAT/UNS and concentrate in CS; CS does not require a letter grade.
If my laptop isn’t working, can I borrow one?
Yes, SEAS Computing has a (small) number of loaner computers that they can loan out for a couple of weeks at a time. They arent’t replacements, just a way of not falling too far behind while you either get your current machine repaired or procure a new one. Email firstname.lastname@example.org to arrange.
Does CS50 have any prerequisites?
No, CS50 does not assume any prior CS or programming experience. In fact, 66% of Fall 2018’s students had never taken a CS course before!
Should I skip CS50 if I already took AP CS A?
Probably not. Most students who have taken AP CS A still take CS50 as it tends to fill in gaps in their knowledge and also introduces them to C (and more!).
Is attendance at section expected?
Yes, as sections are meant to be a more intimate, interactive opportunity to master the course’s material. If ever unable to attend your own TF’s section, though, you’re welcome to attend any other!
When is CS50 offered?
CS50 is offered primarily in fall term. All students, including concentrators and non-concentrators, are encouraged to take CS50 in fall term. However, concentrators and secondaries unable to take the course in fall term may take a spring version of CS50, aka CS50s.
How does spring term differ from fall term?
In fall term, students are expected to attend live lectures as well as live sections. In spring term, students are expected to watch lectures on video (produced in fall term) and attend live sections.
Academically, the terms are equivalent, but the fall version of CS50 includes cultural traditions as well.

Can I simultaneously enroll in CS50 and another course that meets at the same or overlapping time?
Yes, you may simultaneously enroll in CS50 and another course that meets at the same time, watching CS50’s lectures anytime online and attending the other course in person.
Ordinarily for simultaneous enrollment, you need the permission of the other course’s instructor, you need to arrange for “compensatory instruction,” and you need to petition the Administrative Board itself. But the Administrative Board has already granted an exception for CS50 itself, which obviates those needs. You do not need anyone’s permission or signature, and you do not need to petition the Administrative Board.
To simultaneously enroll in CS50 and another course that meets at the same or overlapping time, all that you need to do is enroll in both courses via my.harvard. CS50 is deliberately listed in the catalog as having no day or time (even though it does meet on Mondays, 3pm–5pm) so that it doesn’t technically conflict with any other courses. (Otherwise known as a “workaround” in software!)
Can I watch CS50’s lectures online if they conflict with some other academic or athletic commitment?
Yes, but be sure to arrange first with email@example.com.
How much academic support does CS50 provide?
Quite a lot! In addition to lectures, supersections, and sections, CS50 also offers more than 350 staff-hours of office hours and tutorials per week.
How difficult is CS50?
For many students, CS50 is simply more time-consuming than it is difficult. Starting each week’s problem set early, then, makes things easier! And the course’s difficulty was also recalibrated back in 2016, per the Q data below.
How much work is CS50?
Although the course’s workload had been on the rise in recent years, the course’s workload was recalibrated back in 2016, per the Q data below.
By mid-semester, most students spend 12+ hours per week on the course’s problem sets, but it definitely varies by problem set, per the below, and student.
Note that, in Fall 2018, Problem Set 3 proved more time-consuming than intended.
