it may help you to make pictures out of the letters, I know this sounds like something a kindergarden project, but it may help you to figure out which way the letters go. just take and look at a letter in a book and wright it so its going the same way on a piece of paper and add to the letter turning it into something else like a car or a face or something, if you have more detail to remember than your more likely to recall something about your picture that will help you to recall which way the letter or number goes.

TRY COLOURED OVERLAYS they work wonders. just google them and buy a pack. my eyes like green.
