The main speed-builders are replacing parts of words with a raised letter. Some of these are at the start of the word and some at the end. After the initial lesson to explain this, and get you started using ‘ing’, we’ll work steadily through them in pairs of one prefix and one suffix. You’ll find some easier than others; keep going with the tricky ones and practise will see them become easier.
There's no more learning to be done but you can combine dropped and raised letters to make some long words really quick to write. Do these a few times - see if you can write each twice in the time allowed as you get used to them. And there's a downloadable version of the Speedwriting Dictionary here to help when you need it.
Test your use of all the raised and lowered letters. See how you get on under pressure with a couple of timed tests and finish with some more reading. If the tests show any areas where you need a bit more practise, repeat the lesson or just the additional section of the list of words from it. Remember to say the words as you write them - it really helps.
