hmm..tough one, what should I do....you wrote that you don't know one single page....so what is the chance in passing the exam? If it is a small chance, you might have to do it as well in your vacation...and even worse... you might miss a great day! IMO, your will have this opportunity just once in a "lifetime".....
If there is a great chance that you'll pass.......skip the exam as well, LOL!!!
