How you will use it
Practise the way that suits you
- Learn as you go. Answer, read why straight away, then move on. No clock, no pressure.
- Or sit it timed. A clock, no answers until the end, and two minutes a question, so you learn to pace yourself.
- Score by topic. See which area let you down instead of one number out of a hundred.
- Go back over it. Read every question again afterwards, right and wrong, with the full explanation.
