Princeton does not offer direct admission to major. So, after being admitted to Princeton, how does one get into CS major? Is it competitive?
Is there a limit on how many students can enroll into CS major? If so, given the high demand for CS major, how do they decide who gets in and who doesn’t?
Is it possible that after becoming a student at Princeton I may not be able to get into CS major?
If you fulfill the prerequisites (see the Paths Through the Major pages on the CS website), you will be able to major in CS.
No. You just need to take the the courses and declare CS as major.
Just wanted to add that not every college has a “one school” concept like Princeton and will allow you to major in any of the offered majors. Many (USC, Vanderbilt, Duke etc.) have separate schools of Engineering that may have specific requirements/a competitive process to declare a dual-degree or inter-school transfer.
Can confirm this from our experience.
