I'm going to university this September. Nearly everybody says "In university they don't try to understand what you've written it is unintelligible." My handwriting is incredibly ugly. I want to improve it by the time I go to uni.
In elementary school they only taught me cursive handwriting. And I never bothered to learn print handwriting. I can write like that but I'm really slow at it.
How can I improve my handwriting? Which exercises I should do?
Practice writing slowly and with good form. Write regularly, give yourself practice pieces. At uni you will be writing FAST, so it'll get worse if you don't keep disciplined.
Alternatively, learn to touch type, and type any work you need to hand in. - if your handwriting is so bad, you may want to make your notes legible to yourself for revision.
It's like everything, practice slowly, get good form wired in, then when you write fast for exams your writing will be worse than normal, but still legible.
