typing speed/casper frustration

i have practiced and practiced my typing but I always plateau at 56 wpm when doing prep match questions. I have tried so hard to get better at touch typing but when I am stressed and under pressure I know I just revert to my wonky typing style, and if I try to focus on touch typing I just get slower. I also HATE the fact that getting into medical school is somehow depending on my ability to type fast?? i am SO frustrated.
