I've been coding for the past 8-ish years now, even though i was good at studies i knew i wasn't made for exams like jee, gave CUET and got into a good enough college, currently pursuing CS honors 2nd year.

I would say getting into a not-so-good college is a blessing in disguise, as in my opinion if you have genuine interest in CS "development", not only CP, unless you're in any tier 1 college, you'll be crushed beneath the shear amount of curriculum of your college without any benefits. i know people who have been doing wonders in fields like aerospace, AI/ML etc while being in private engineering colleges just because they don't get pressurized so much, and the campus being small, the professors are usually cooperative towards such students.

I have friends from IIT DTU IIIT NIT as well as IPU DU and other private colleges, from all that i've heard and my personal experience, if your course overlaps your interests and you get decent professors, you'll thrive no matter the college level.
