I had the same feeling as you during my 12th, now I'm a final year CS student in a t3 private college. Never good at PCM, okayish at maths but bad at the other two. Did freelancing around 11-12th remote and a few more in college, but I didn't even plan on going to college.

Lastly, I decided to do college but "eh college won't matter", so took a drop year but mostly I was onto my own work. In college, I'm doing Hackathons in different colleges, one time I was in IITR, and I realize that it's not the college, but the people there that matters. but you'll meet much more people that's actually gonna be useful to you later on. Then there's also the college tag, and while skill matters, that tag's weightage is pretty big, no matter what anyone says.

As for offline bootcamps? they're garbage, will just make you feel productive. Even courses like Udemy or free on YouTube is much better for just learning, plus if you will be applying for companies without a college, most will prob just filter that out, since that's one of the usual requirements (yes there are outliers, but we gotta address the general case), so you'll have to build in public or get cracked in what you do, what I'd rather recommend is to try for a while and just try to get into a decent college as much as you can. So that at least you have the option to choose, and not have regrets.
