CS50's Introduction to Computer Science

They were not kidding when they said the course was "demanding". I spent at least 2 hours daily working on the course and each course week took me a month to complete. It was exhausting a lot of the time. The problem sets are designed in such a way that one is forced to read and do further research to accomplish them. The sense of satisfaction I gained from completing each problem set was tremendous and even though the learning curve is steep (to say the least), I am now comfortable in my understanding of the basics of computer science and in coding in C. The web design module was probably the most fun even though for me personally it was the most demanding.

I guarantee you will be pulling your hair out sometimes if you take this course, but you will have tremendous fun most of the time and the sense of accomplishment is exhilarating!

This course is not for beginners. I wanted to learn programming for fun, to understand what my husband does, and learn something new at a leisurely pace. But introduction means nothing, you jump right into problems sets that are extremely challenging. The instructor speaks at a lightening speed, bouncing around ideas, as if talking fast will keep me interested. It does the exact opposite, I'm like "what is happening?" I also consider myself a studious person and a classroom teacher and this didn't feel basic. For someone who's never written any code and learning for fun, my frustration level was way too high and preventing me from moving on. I needed more scaffolding/building blocks (again this is supposed to be an introduction) because I just wasn't understanding what he was talking about no matter how many times I looked back at the notes, lectures, slides; I couldn't piece it together and had to find another more suitable course for my level.

I wholeheartedly recommend CS50 to anyone seeking a solid introduction to computer science and programming. It will not only equip you with the necessary skills but also ignite your passion for the subject, setting you on a path towards a rewarding career in technology.

This course takes you through the proverbial weeds of computer science. We start from an bottom up approach, learning about how computers only understand binary, then how a layer of ASCII makes more intelligent; it's extension with UNICODE, how in modern world we arrived at different languages, we get to understand how layer by layer everything is connected and it goes back to binary. After this we learn literally from SCRATCH different programming languages, difference and more importantly similarities between them. All of this in only the first lecture. And there's more to each lecture after this.
Given we only touch the concepts but I think that that's what introduction is supposed to be about and nevertheless if you follow the P-sets and assignments, you are bound to make the time spent on this course more productive than any other time in your life. Do I think this course is hard? - Well, Sure; Are the problem sets difficult? - Definitely; Will it require too much time studying outside of lectures? At this stage I will say, you will spend as much as 10 times the time spent on lectures, to study outside material. I know a lot of you will be discouraged but let me assure you, not only will you be proud of your progress at the end but learning this way will also make you self reliant and ready for future challenges in computing world. There are communities for this course which will help you only if you ask. If you want to follow this course I suggest you give your everything, kitchen sink included. A sincere effort will take you a long way. What matters at the end is where you end up at the end of course compared to yourself at start, and that difference is unfathomable.
Credit where credit is due; It takes great effort and commitment to come up with quality course like this and David Malan, being the great teacher that he is, does it year after year, semester after semester, and makes it look ridiculously easy (I guess that's how Legends like to do it.) The whole team of CS50 and CS50X has put unbelievable amount of effort in this course and it can be seen in every small detail in the course. Hats off to them.

My first coding course. CS50 holds a special place in my heart.

CS50 is hard. At least as a programming newbie, I thought it was hard. I screamed at the screen "How the hell am I meant to know that!" more than once.

But real life programming is hard and CS50 teaches you quickly the number 1 rule of programming: Google is your best friend.

Should they start with teaching C? Maybe? Maybe not?
At least by doing C at first you won't be intimidated by lower level programming languages, even if like me you switch to something like Python later.

Tips for students:
- Learn how to Google things (don't search "CS50 problem answers to set 5" instead use things like "how to change the last item in an array in C")
- Watch all the short videos, not just the long main one. By the end of the course I much preferred the cheeky smirks of Lloyd's videos over Dr. Malan's clinical and overly polished deliveries.
- Use the Reddit and Discord communities to get support when you're really stuck
- The course is hard, it's okay to feel frustrated, you feel great when you complete it finally
- Don't leave big chunks of time between study sessions
