The things I used to prepare for the exam: - "Off course" the HFSJ book. Almost, yes ALMOST, everything you need for the exam is in there. I got 74% on the final mock exam, so the 20% rule almost applies here. - Bought the Whizlabs SCWCD simulator. It provides good questions and more difficult exams then the real one. Though, I was a bit dissapointed with this product. It contains quite a lot of errors, not all grammar mistakes, but also wrong code examples etc. This product needs an urgent update! - Did a couple of small mock exams on the internet.
In my opinion the exam was not that hard and does not go as much in detail as I expected. Don't get me wrong, you still need to study a lot to make a good score!
