Welcome! CSCI 200 centers around data structures, the design and high-level analysis of algorithms for performance and social-impacts, and good programming practices using a combination of object-oriented (OO) and functional programming (FP). Each of the prereq courses (111, 112, 150, 170, or 190) teaches one of these two programming styles; in the first two weeks of the course, you’ll learn the foundations of the other style so we can build on both throughout the semester.

This site is for the Spring 2025 offering. If you need materials from an earlier semester, see the previous offerings page.

Lecture Logistics

We meet on MWF 11-11:50am in Salomon DECI Auditorium. Lectures involve several exercises in which you will work on a problem with your neighbor before we come back together to go over questions. Most of the lectures are better-suited to pencil and paper notes than coding along, but you are welcome to code along if you wish.

We meet together as one large class on Wednesday, January 22. From Jan 24–Feb 3, we will meet as two separate tracks to cover the language foundations:

• Coming from CS0150? You will work with Prof. Kathi Fisler in Salomon DECI Auditorium.
• Coming from CS111/112/170/190? You will work with Grad TA Elijah Rivera in CIT 227.

Starting Feb 5, we’ll all be back together as one lecture section in Salomon.

Communications

We will be taking questions in real time during class via Ed Discussions. If you have the course in your cart, you should have access to Ed and the lecture recordings in the Canvas Media Library.

Post questions on Ed. Personal or registration-based questions should be sent to Kathi at cs200-profs@brown.edu. This is a dedicated course inbox that helps Kathi keep track of mail.

Exams

There will be three pencil-and-paper exams this semester:

• Exam 1 will be at 7pm on Wed Feb 19/Thurs Feb 20 (offered both dates; you come to one)
• Exam 2 will be at 7pm on Tues Mar 11/Wed Mar 12 (offered both dates; you come to one)
• The final will be 9am-noon on Monday May 12th

Barring significant extenuating circumstances or taking the course off campus, you must take these exams in person. Having booked early flights home will not count.
