Post a picture of your handwriting?
So my parents are always like, "YOUR HANDWRITING SO STUPID LAH YOU GOING TO FAIL DUH WRITTEN TESTS" and I'm like, "It's not that bad..." and they're like, "IT LOOK LIKE DUH CHICKEN STRATCH ON DUH PAPER" and I guess you can't really argue with that. I mean, I have lost marks over written exams. lol
I guess this is pretty easy if you have a tablet. If you don't have a tablet, write it on paper, take a picture via webcam, and save it.
If you don't have a webcam, use your phone. And if you can't upload pictures on your phone to your computer than maybe you shouldn't be owning a computer/phone at all. lol
