Interactive multi-choice activity for practising the various grammar points. 30 questions are embedded but the activity will select 20 items at random to practise each time it is opened. It will also arrange the questions and the multi-choice answers in random order. With any luck it will never be the same twice. PS In response to the comments below I have de-bugged the original file. This one should be error-free. I've changed the background colour of the exercise too.
