I understand what you’re dreaming about.
You’re a “maybe.” But that doesn’t say more likely to get a yes or a no.
Going to college at 22/23 doesn’t mean you hang with drunk freshmen. Plenty of older students put their heads down and focus on the work. It’s one reason colleges sometimes like older students and have the programs to bring them in and ensure support.
The issue is, not sure you know what the gig is, today, what will matter for your app. Look into each college’s program for returning or non-traditional students. Talk to them. Understand that you will be viewed differently than a dependent 17 year old. They will want evidence of your academic commitment and a certificate program may not be enough. These are often taught by adjuncts and not the same as having more purely academic courses behind you, with a record of top performance.
A successful business is also not proof of your ability to take on academic challenges. (It does show maturity and maybe resilience.) I really suggest you take some community college classes or something in UCLA’s regular course list, if they will let you. You need to build a record that shows you are capable of meeting their very real classroom expectations, including any cores.
Harvard? As you grow, what will likely matter is a degree. (Some can be successful in business without one, but this is CYA. You may get injured or want to leave your own company and work for the man, different challenges, different gains.) it doesn’t matter if you start at Santa Monica or a community college and possibly transfer into another school, later.
You need income, no need to quit the job. This American dream thing is about putting in the effort. Not saying, well, if it’s Harvard… Think about it. Do the research.
