Soooo. As I'm really into Tarot ("I want to be a pro!" level), I'm willing (and sometimes able) to spend some of my money on courses.
I figured – why not start a thread about paid courses? Disclaimer: I am well aware that you do not need paid courses to be an excellent Tarot reader. But I miss school, and I miss the structured learning and so forth. So I turn to paid courses.
My favorites (that I've done) are:
Tarot Card Success (by Sal Jade, on Udemy)
Awakening with Tarot (by Seda Ünlüçay, on Udemy)
Beth Maiden's Alternative Tarot Course offered some great insight and helped me build confidence as a nonbinary Tarot reader, I no longer necessarily associate Kings with men etc. As far as I know, that particular course isn't currently available & as far as I know, it's going through an overhaul & as far as I know, it will be available eventually.
The thing about Udemy is to keep an eye out for sales. A $200 course might be $10 during a sale, so I'd recommend grabbing a course when it's on sale.
I'm currently eyeing Ethony Dawn's Tarot Reader Certification course, but that's going to have to wait until I see if I can get a grant for it as it's quite expensive. (There's an organisation in Finland that offers grants for disabled and mentally ill people to study etc., and they require a specialist's opinion on how the particular course would aid me in life. My psych team will meet in June and then they'll discuss how to write the opinion and then they'll write it and then I'll send the application in and then I'll be terrified until the organisation can make a decision on it. Scary.)
