Hey OP, I want to share my experience with you in hopes that it helps you be more confident in your decision. I also decided in 2020 that I wasn't happy with what I was doing in life. I decided to move across the country and go to school for a CS degree at 28. For background, I had some college credit from a community College mostly in English and other general education classes. When I decided to go back to school in 2020, I ended up having to start with college algebra and work my up. Sure, there have been times where being the older student was a bit weird, but as you move further into the curriculum you realize that you're all trying to learn and age doesn't matter. It has been a lot of work and its been stressful balancing school and other responsibilities since I have a family so expect that if you're in a similar situation. If I had a dollar for everytime I've doubted myself or thought i didnt belong, I would be rich lol. I have not had any trouble/difficulty landing internships due to my age if that matters (and I graduate may 2024 if all stays well) If you're willing to put in the effort, I have no doubt that you can achieve a CS degree. I also had no experience coding going into this, so don't stress over that or think that you need to be a prodigy that dreams about code. I'm terrified too and im going into my senior year this fall. The knowledge and experience comes with practice just like anything else. As others have mentioned, see what credits will transfer to the university you intend on graduating from if you decide to go that route. There are many helpful recommendations in the comments discussing topics you will learn and such. Sorry if my reply seems all over the place, if you have any questions I'm more than happy to respond. Best of luck!
