Hi Arun,
Take it cool.. it's not that difficult. I read the HFE twice. Also, I took notes while I was reading the book. Don't forget to take notes (most important and useful thing i did ), that will help you during the last minute lookup.
I did 5 mock exams using INESystems, a couple from jdiscuss.com and all the exams in ejbcertificate.com. Each time I make a mistake, I understand the correct answer and if that's something new, I add that to my notes.
Take the HFE final mock exam only a day or two before u'r sun exam. Well, HFE is fine for you to pass. But if you get time, do read the spec also. After reading and understanding HFE, reading spec will be so... easy.But you may find a few points that HFE may not have mentioned.
Pay more attendtion to EJB-QL and Message Driven beans. Understand each and very line.
Learn each element in the DD, it's important. Refer to valentin's cheat sheet for this (

Understand the roles and responsiblities .. it can be a bit tricky in the exam. Read the spec and also Mikalai Zaikin's study notes (

For the exam, spend more time for drag and drop ques and try to answer it correctly at the first time itself. If you try to review it later, it resets all the answers.
All the best
) and would like to know more about your preparation strategy wrt the mock exams that you took and any other tips that you might deem useful.
