Exam questions will be on the lines of the exam objectives, try to find out whether exam objectives say that you need to have knowledge of ~ n' all. The practice exams may test you a bit hard.. it's good!
Thanks for the advice, im taking it to mean that the mock exams will ask a broader range of questions than the real exam.
Ankit: I haven't really found any difference between Enthuware and Whizlabs. Whizlabs looks more professional when it up and running than Enthuware (which just looks like basic Swing). The questions are much the same. They both let you answer questions based on your area of weakness and whether or not you want easy/tough/very tough questions. Enthuware has a lot more questions. I find in the Whizlabs I always seem to have seen the question before.
So does that mean the questions in the real exam - you have to scroll through to see the entire question. I found it very hard to scroll and understand the question. I hope the questions can be read without scrolling
