Thank u all javaranchers.
Want 2 share some experience.I got 2 questions which had none of the options right & i was asked to check 2 of them.So,i checked 2 options which were near 2 correct.But in the end they were considered wrong.I think so sun are not aware of that.They shouldn't include like that questions.
Anyway my advice to those preparing scjp is that,
Khalid moghul's book is one of the best books we have.
JQPlus & Jwhiz can boost your confidence.
and of course above all JAVARANCH is the best tool to clear your doubts.
