One more bit...
One more bit of advise. I don't know whether it works or not but I didn't it and I passed (my practical at least and feel good about the written). Put your books away at least 24 hours before your test and go do something that is fun and that you enjoy doing. Kinda takes the overload off your brain.
The simple believeth every word: but the prudent man looketh well to his going. ~Proverbs 14:15
