Finally I cleared the exam with 91% (first I misread 61!).
Thanks to my wife/daughter (for support/patience) and internet.
It took me two weeks to prepare of which most of my time I spent on javaranch+maha (30%) and mock tests(40%). I hardly referred to any books (just RHE ~10% and couple of hours on JLS). Notes from Nityanand Mukherjee provided excellent last minute revision.
I infact scored more in the real exam than any mock tests (even though I found it tougher than most of them) - may be I was more focused/careful - and my daughter was not pulling my hair
Exam tests your understanding of the concepts and does not try to trick you (keep away from tricky mock tests - they can really confuse you). Marcus Green,Jxam,Jargon were the closest in terms of the type of questions (real is much tougher though).
Go thru archives of Java Ranch Certification Forum and Maha's site. That should clear most of your concepts.
