Some of the mock questions on this web site are unbelivably tricky...especially the "difficult exam". It hasn't much helped me to boost my confidence. I tell myself that I would do a lot better if I knew how many correct answers to choose, like the real exam is supposed to be. I'm curious if anyone who has passed the real test has found this to be true for himself.
I think the intend is so you can develop a thorough knowledge on the subject, not just stuyding it to pass the exam. Yes, they're hard because of that nature but they're really helpful to give you that 'reality check' to see whether you're ready or not. If you think that's hard, try the mock exam in HF EJB. I got only 39 right answers the night before the exam! Talking about 'reality check'. Since it was too late to cancel the exam and I had been in agony studying and coding for like 2 months - i decided to finish it once and for all (so i can watch sweet 16 NCAA games!). I got 59/70 on the real exam. good luck
