Yes(ish). Maybe penmanship wasn't the right term though. As part of further testing I had to do, one of the things was copying designs onto paper using a pencil. Since I haven't been using pencil/paper much since school (app 3 years), that was the one outlier of all the tests. I was much slower than if I had been practicing for a while in preparation (Or writing letters, vs. e-mails). Adhd is no longer an issue, and the letter from the RMO reflected that. Now it's the speed of my writing which leaves me medically unfit (which, when looking at previous tests, varies greatly depending on frequency of use). Obviously I'm going to work on improving my writing speed, re-take that section of the test, and appeal. I just wanted to know what kind of precedent there is for this situation.
Emphasis added in the hopes that someone might learn from this.
