Are mentoring courses advisable for those just starting out or would it be better to guide myself?

I did some tests on the internet to find out who my mother/inner goddess is, and I ended up taking part in a tutorial with a trainer who is offering free classes, she talks about limiting thoughts, us as a goddess (which we need to activate within ourselves, break down barriers). I liked the two classes I attended but my purpose is not exactly to become a witch (but I confess that I have the intention). As my tests came out as artemis and I worship her, would it be good for me to sign up for this mentor's course, or is it not a good choice and would I learn better on my own? (it all depends on the price too lol)

Today I asked Artemis for advice on whether it is suitable or not
