Tess and I had another "Exam" this evening: and this one we passed! We did a lot of in-hand-work/laps around the ring, and she was SO CALM, despite several simultaneous lessons (and a nervous horse she usually gets spooky around). She had a couple moments at the start where she kinda froze in place, and then we went about our business with no fuss. (Even the trainers noticed "She is very quiet tonight".
There's a bomb-proof pony in there that's gonna emerge eventually :)
