Hi Rina:
you are absolutely correct about whizlabs.. I am also preparing with that. I am almost done with it and searching some more mock exams.
My experience with Sun's e-practice exams was not good. Like I purchased their Web learning course a week back but it didn't worked for me. The Sign up page was not taking my username and password, so today i am asking its refund.
Since I am going to take exam next week. I am in panick to have some more questions to practice.
Regards
Swapnil
