Any advice for writing a page in 10 minutes?

I’m in the middle of exams right now, absolute nightmare, I know I’ll be getting terrible results because writing essays is so hard for me. Sucks there’s no dysgraphia accommodation for my exams.

Anyways I have an exam tomorrow that I actually care about, I really wanna do well. I know the stuff, but if I wanna do well I’m expected to have a 4-5 page essay done in 45-50 minutes (x2 essays in the 1hr 40 min exam)
My main struggles are hand tensing and always running out of time no matter what — I dont just start writing poorly I lose the ability to form letters. It honestly feels like when you try to yell or run in a dream and can’t. my handwriting goes to hell even if I try to be neat, I always make mistakes like having one letter of a word randomly really far away or accidentally merging letters into one symbol. And it feels like no matter how hard I try, trying harder makes it worse, and even if I push through I still can’t write fast enough to finish essays usually.

I know I can’t cure these things or fix them overnight, just want some advice if there’s any tips or tricks that you guys have used for essay writing.
