Suddenly a bit paranoid I'll fail all my essay subjects because my handwriting is shit

I'm worried my teacher has just gotten used to it. I know it's better than it was before and my friend managed to read a good chunk of a question I wrote under exam conditions (he missed a few words, but maybe he could have figured it out with more time? I basically just said it at soon as he faltered) and I've assumed it's fine because I've not been told I need a laptop.. but... that's not the point.

My handwritings never been that great, I remember being told in year 5 I had to write in cursive or I'd fail my sats - not that that ended up mattering - but yeah, just a bit of last minute fear.
