I do the Marcus Green's 3 mock exam, skip all the threads about GUI & IO, just got 75 %~ 80%, if I take the really exam(scjp 1.4), can I pass? Many people said the first time when they take Marcus's sample test, the % they get is close to the % they get from the real Exam. But the 3 mock exam is design for scjp1.2, is it suitable to 1.4? I don't know whether it is the time for me to take the really exam or not, I want hear some advance of who passed the scjp1.4. Thanks in advance.
I think, the demo version of J@Whiz is Deliberately difficult, if you score with Marcus 90+% you maybe score 60+% with the demo. Try Dan's mock exams, they are Excellent and free, if you want to take the 1.4 exam you must study collections in a better way, assertions, hashCode() and equals(). Also I heard many Thread questions are encountered in the exam and they are difficult, so you should stress on Thread's as well. HTH
