Whenever i have someone ask me where to get started on CS - i give them a few options tiered to try and ensure some stickiness/higher utility for them specifically. ~Some…

There are many resources these days. And that is also part of the problem. Because organization is very important. Some of the resources you can try are: Path to a free self-taught education in Computer Science! https://github.com/ossu/computer-science Foundations of Computer Science http://i.stanford.edu/~ullman/focs.html MIT OpenCourseWare https://ocw.mit.edu/search/?d=Electrical%20Engineering%20and... and so on. Try to stay clear of coding schools, dojos etc. However, it would work best if you have a project idea in mind. Abstraction is your friend. You don't need to be an engineer, but an engineering / problem-solving mindset is very important. There are quite a few well known programmers who don't have the traditional CS background, including yours truly. I self-taught myself and keep learning and writing programs. Feel free to reach

In What's the Best Tech Field to Learn, and Get Involved In?

I created a smart planner app at a similar age [1] and I'm now in my third year of university studying CS. I've also had a taste of industry from building a journal app as a freelancer [2], interning at a department of my uni [3] and interning at Wise [4]. - The whole js, css, html, react stuff sounds more like a beginner web dev bootcamp that should last a few months rather than a 3-4 year CS degree. Avoid that. - Sometimes YouTube is great. E.g., a playlist from a Cambridge lecturer [5] was immensely more valuable than the live lectures I was being delivered alongside 200+ other students. I don't think lectures are efficient but I typically have a mix of lectures + labs + coursework and now, a substantial individual project supervised by a researcher. I'm excited for the future of edtech and programs like OSSU [6] are great if the focus

is purely on absorbing CS content but its limited. Something else I found is that the modules I dreaded the most and certainly wouldn't have opted into had they been optional were the ones I learned the most from. Who knew that an Interaction Design class would be so relevant for doing customer discovery in a startup. - No doubt that you can also have an income while studying. - Pick up an internship to learn from experienced software engineers. - The life experience is something I'll miss dearly, be it sports, socialising, dipping into the startup culture (We have an on campus accelerator). - I stress more about turning down jobs than worrying about not having one. If you have access to a quality CS degree that doesn't cost you a kidney then go for it.
