I've had PMs asking the same, posts in different topics...Even though i wanna help, I just can't go into specifics. If you go through GBotley's blog, you'll find every hint you need. The questions on the test are different anyway, so I would advise you to practice your mental arithmetics more than anything else, that will help you as it helped me.
