I'm 24, and I've been a member of a few orgs, and I've spoken with many more.
None of the parties I've talked with (with the exception of PCUSA and APL) have any serious focus on education. PCUSA has a relationship with caleb maupin so I'm not gonna touch that, and APL is kinda hard to get ahold of. I did interview with them a couple years ago, but I was rejected and told to read more theory which tbh, was true I did need to read more theory, but also doesn't inspire confidence that they can actually build up their party.
CPUSA is in bed with the democrats, PSL seems to officially hold no stance on stalin or trotsky which is just...weird, FRSO spent a week trying to convince me to get a job at UPS so I could work with the teamsters (which is valid but I wasn't interested) and then just never talked with me again. Talked with CWPUSA recently which is a newish party, required I already be involved in a mass movement. Fair enough, I just don't meet those requirements.
I'm starting to feel a bit hopeless about it all. When I was in DSA & CPUSA, I atleast had friends that I could talk about things with, now it feels like I'm entirely alone. I've only been at this a few years but it feels like decades. Nothings been accomplished, I'm still a midwit when it comes to theory, and I don't feel like I can trust myself let alone other people at this point to figure out the correct course of action.
Silver lining, I did find a few publications I like through this process. Red Phoenix(APL), New Worker(CWPUSA) and Red Clarion(unaffiliated but many are former cpusa members). They are all consistently good and I might end up purchasing a subscription to help with them at some point, but idk, its definitely not enough.
