- The first thought that came to my mind was to write with your other hand - that's a sure fire way of disguising your writing.
- Also, why don't you try gripping your pen differently? Clutch the pen in a fist and write like that.
- How do you write? Do you print it out or do you use cursive writing? Do the opposite of what you normally do.
- If you always use the same colour pen, use one with a different colour
- If you tend to write slowly, write it out as fast as you can (or vice versa)
- Write it on a bus/in the car when you are constantly bumping around
- And if all else fails, get someone else to write it - parents, friends, siblings, neighbour, etc.
