I'm a visual learner. I really like the diagrams of dressage tests that I've found online and prefer them over the written dressage directions for test prep. When I was trying to memorize the BN A test for my last combined test, I could't find a diagram. At least not a free one; there's probably something I could have bought available somewhere.
Since I couldn't find what I wanted, I made my own. I find them pretty helpful especially since I can just save them on my phone and don't need cell service to look them up later. Feel free to use these and share if you want to.
