Really? Is that true? I know there is a correlation between test anxiety and overall anxiety. With regard to surgeons, 1/4 surgical residents placed in the 90th percentile or greater (compared to general population) when surveyed for psychological distress following a switch to an 80 hour work week (was nearly 2/5 before the 80 hour limit) http://www.ncbi.nlm.nih.gov/pubmed/16153421 so it seems counter intuitive that there would be no correlation between test anxiety and surgical performance anxiety.
I’m sure you could learn to overcome your test anxiety. I would definitely do that ASAP too.
