Memorize the test!
I am no expert, but personally I don't see anything wrong with practicing your tests! I rode mine many times before the show. Winston didn't anticipate anything, except for the halt on the centerline, (find me a dressage horse who DOESN'T know that you halt right there???) I don't really see anything wrong with it, as long as you're not POUNDING it into their heads and it's the only thing you do when you ride. I agree, how are you supposed to know how to ride it at the show if that's only like the third time you've ridden it?? The worst that's going to happen is they are going to anticipate you, right? Well, that just means you'll have to ride better to keep them focused, maybe even switch it up in the middle of your test, show him you don't ALWAYS circle at E! What do you guys think, do you agree with me?
