I was just wondering how reliable the cheet-sheets/Troytec OCP docs are for the real tests....anyone have any experience with them as to whether they are a good guide for questions on the test? How are the STS exams then also? I know that the cheet-sheet/Troytec docs for MCSE are right on the money as long as you understand the answers (from actually trying it out or work experience) .... but it was absolutely a good investment to get those for the MCSE exams. Anyone have any thoughts?
