How long does it take to complete cs50?

There is no to-the-hour estimate from Harvard. They do state problem sets take 10–20 hours to complete. With 8 problem sets, ~5 hours of video content per week, and a final project, a ballpark estimate would be somewhere just north of 200 hours.

What should I do after cs50?

If you have taken CS50 and you're interested in pursuing computer science further, then you can learn more. Perhaps the most important skill that CS50 teaches is the ability to teach yourself.

Is cs50 enough?

It's the best start. CS50 is a very challenging class. However, when you complete it you will be set up for success in any kind of programming you may choose to pursue. I cannot recommend enough.

Why does cs50 use C?

C is just about as close to a computer's hardware as you can get before you have assembly language (which would be too arcane, I think, for an introductory course like CS50). C is also a small language that, by mid-semester, students have seen nearly all of (except for, e.g., unions and function pointers ).

Does cs50 get easier?

It doesn't get easier, but the more you learn it gets so rewarding - even little things like understanding a few jokes in TV shows I might have not understood before. Learning programming is hard. But, in my experience, it is only particularly hard the first time you learn a language.

Should I learn Java and Python?

If you're just interested in programming and want to dip your feet in without going all the way, learn Python for its easier to learn syntax. If you plan to pursue computer science/engineering, I would recommend Java first because it helps you understand the inner workings of programming as well.

Does cs50 teach Java?

But CS50 will teach you what a pointer is, which is what's really important. There are other ways to learn, if you just want to learn Java. There's Java-specific tutorials on the web, and you might be able to plow through them a little more quickly.
