Hi Ritu, and Pavan,
I cleared My SCJP with 77%.(refer to my earlier post in the same
thread). I had studied reasonably seriously for nearly 6 weeks and played around with
java for 2 months. I have an programming background, but I was running against a deadline.
My advice to u both:
If the percentage are really important, make sure you get more than 95% in mocks, but probably by now you would have gone through atleast 7-8 ones(an approximation). What happens later on is that you start scoring not because the concepts are clear but because you know the questions. At least that is what I saw happening to me towards the end

Make very sure that your fundas are crystal clear. I would include following objectives in it:
1. Declarations and Access Control
2.Flow Control and Exception Handling
3.Operators and Assignments
4.Overloading, Overriding, Runtime Type and Object Orientation
5.Language Fundamentals(except event Listeners)
What I have found is that the difficulty level for real exam questions is much higher for these than that found in mocks. For rest of the topics, the difficulty level is nearly same. Lots of coding should help. Esp. If you take a working code and then twist it around to see which variations work and which don't. and why they don't. That will help like nothing else.

The questions that I encountered were not tricky or extra long, but they were worded in such a way that only if you had your concepts very clear, then you could answer them.
The exhibit button/window is not that distracting. In fact you can use the "Tile" button in the exhibit widow to tile both the windows horizontally on the screen, Question window goes on top, and code below. so you can scroll and read both at the same time.
Time should not be a problem. If you keep an eye on time and mark the questions where you are taking more than a minute, you will be able to solve most of the questions in time enough to go back and preview the marked questions. Remember, all the questions have same weightage, so if you find yourself spending more than a minute on any question, mark it and come back later. The next question might be easier and ensure your passing

Thanx for going through this extra long post...
HTH and all the very Best
