I’m thinking a 30 year old transcript with a ~2.0 GPA isn’t going to move the needle much.
The big downside at my school is the fee for this approach is the regular cost of taking the course, paid before you take the test, and nonrefundable in the event you don't pass. But not passing doesn't appear on your transcripts, so it only dings you financially
Also, you're only allowed to test out of a handful of requirements for your major. It was explained to me this is so no one can effectively "buy a degree" over only a semester or two.
But I've found most instructors willing to let someone in their classes who doesn't have formal prereqs who has relevant work experience
I'm in a similar boat in that I'm in my 30s now back in school. when I was 18 I dicked around for a couple semesters and dropped out. Thankfully my old community college has a system for expunging bad grades that are more than 7 years old, and I don't think that's very uncommon
Then once you have all that out of the way, you can take the upper level classes in CS at the university instead of the community college.
There were exceptions that were worthwhile, but it was largely an exercise in documenting my existing knowledge. I couldn't test out of things, and most subject had compulsory exercises, so I spent a lot of time basically proving what I already knew rather than learning new stuff. It was clear to me in advance which courses I could have easily skipped, so from that perspective I would not have skipped useful knowledge.
That said, of course the problem is that to give me an actual degree the university needed to know I actually knew those things and verifying that only with tests is hard to get right.
