Caveat: I am not answering your A or B, but endorsing choice C.
Background: I selected and committed to Andy as my primary influence back when it was just blog posts that I had available.
So, yes, I recommend Andy's Thirty Six Cards. If it again becomes available, his online Cartomante's Cabinet Course gave me a huge boost forward. In the meantime you could use the exercises in his book and repeat them with other readings as you work through the book. Best case scenario, you do your own readings for queries here that have solid, after the fact feedback to check your reading against.
When available, a great advantage to the online course is that you can see how other students are reading. I learned from both "Oh I wouldn't have thought of that" moments, and from disagreeing with a reading and analyzing why -- privately.
For even further study, Andy also offers one-to-one tutoring.
This is not a paid endorsement. LOL
