In my opinion, your claim of not being able to afford the tests is suspect. You apparently train and show Arabian horses. Here, from your bio on this site:
Biography
I train and show mainly Arabian horses, my forte is English Pleasure but I also do Dressage, Western Pleasure, Hunter Pleasure, and Halter. I love to draw and read books and am working on starting college to get my veterinary degree and be a herp vet
I've owned horses and these days the saddles, bridles and other stuff is pretty expensive. You could sell off some of that for funds if you thought the tests were important enough.
I think this is just another delay tactic.
