Unrelated to your question - I'm sure @remlaps would love to see you in the STEM community - https://steemit.com/trending/hive-109160
Back to your question... assuming you're referring to the CryptoAcademy Community, they used to run courses with an instructor - @kouba01 is the one who I noticed the most.
I don't know what the crypto academy's become now - like much of the platform, it appears to be primarily contests. So I suppose the answer to your question (like every question) is "It depends"... what do you want to get out of it?
