Well in general web3 projects have been disappointing for the most part, so it's not surprising why a lot of programs that say they "teach" you about it produce rather subpar results. Not to mention that most of what I've known was about a 3-4 hour short webinar that just endlessly talked about web3 definition of terms, so maybe I'm just biased.

Personally, I'd much rather just go self-study imo, there's a lot of materials out there that may not point to web3 technology, but can help you at the very least pinpoint a starting point. They're mostly related to coding stuff and there's a LOT of those online, so go from there.
