I'm not sure Paul will still agree with this suggestion
, since there were originally one or two incorrect answers found in their tests (I certainly brought at least one to their attention while I was doing the pre-course study for my DSC1). However, to help get through the exam by practicing the entire bank of questions the 'written' tests will be taken from, I found
http://www.dsctraining.org/ exceptionally helpful. I repeated the whole exam tests time after time until I was consistently scoring well over 80% each time. As the site is a £10 monthly subscription, you don't need many months so long as you commit to some intense study. I paid for two and needed another 7-10 days I think it was from memory and I can't remember the exact reason why, but the site owner even kindly extended my subscription for me for those extra few days free of charge.
Regardless, enjoy the course, Paul really is an absolutely outstanding instructor, interesting, engaging and even injecting humour when appropriate. Best of British with a first time pass also.
