Aditi,
I also took the online (free
)Exam. It covers more OO topics than in SCJP2. The level of difficulty in the 2nd part of the Exam is moderate I think. You can use this opportunity to
test your knowledge with qstns which asked comes under SCJP2. I used this just to find out which area we need to concentrate more not counting the final score.
