Is the Harvard cs50 course actually worth it ?
Unless you need the certificate I’d say just follow the course and go the exercises for your own learning. It’s super interesting and worth it, but also can get really hard for new programmers. More on reddit.com

January 15, 2025is Harvard's CS50 a good course to start off with?
Yes I highly recommend it. It's what really got the ball rolling for me in terms of computer science. The way they explain the topics is very clear. They get you working on programing projects and problems right away aswell which in my opinion is the most important part. More on reddit.com

May 7, 2023a friend of mine said you should go through Harvard's CS50 first then other 'heavy' stuff, when I asked why he said "just do it". Please tell me why😭
It's the first year, first semester course that Harvard computer science students do. It's a great introduction to all the basic topics of CS and gives a very good base to start from regardless of which direction you intend to take with programming. I'd also highly recommend you do it first. Apart from that it's the most fun, most professionally put together course that I have come across. Plus it's free. More on reddit.com

CS50 is free, you don't need to pay for the certificate. And, is it beginner friendly? Sort of... i guess. It is meant for beginners, but some of the problem sets there are really hard for beginners. Not impossible though. But it is also where I started, and it definitely helped improve a ton. I think that the difficulty is what makes this course fun and really good, as you can definitely see yourself improving as you move on the weeks. I highly recommend it! Do the course for improving your skills though, not for the certificate. The final project you'll do there is probably worth more than the certificate.

r/learnprogramming on Reddit: is Harvard's CS50 a good course to start off with?
May 7, 2023 -
Hello, im new to programming and i have been doing cs50 now entering week 6 python. I had no idea where to start and got recommended this course. I have almost still no clue what im doing, in the problems and labs i always need help and could never think of an answer and still continue and now wondering if i should even bother learning it. I sometimes feel like im wasting important time of my young ages to learn what to do with life. Just wanted a tip if someone had been in a situation like mine and still continued and succeeded. Ive always had a thing in mind if i dont stop, there will be no other way but learn and succeed. Thanks!

Struggling with problems is good. Seeking help is good. The big question I’d ask is: are you learning? Could you go back and do weeks 0-5 without the help? If not, then you might be leaning too much on the help. Otherwise, keep up the good work!
