The curriculum will vary by university. I remember taking these classes for an undergrad CS degree: - Structure and interpretation of computer programs - Data structures - Machine structures - Digital circuit design - Operating systems - Programming languages and compilers - Algorithms - Randomized algorithms - Parallel algorithms - Computability and complexity - Databases - Computer and network security - Discrete math - Linear algebra - Number theory - Numerical analysis I'd pick a school that was good in several areas, then take the entry-level CS courses. If you like them, stick with it. If not, switch to another major. Someone already mentioned this, but a lot of course material is online. For example, here are some from MIT: http://ocw.mit.edu/OcwWeb/Electrical-Engineering-and-Computer-Science/index.htm http://ocw.mit.edu/OcwWeb/Electrical-Engineering-and-Compute...
