Hi sruthi !!!
I think HFSJ is more than enough to pass the exam.
The preparation's time depends on how much your are confident with developing web applications in
java. If you have developed web application in the pass, you can take 3-6 weeks four the preparation. Otherwise you could need more time.
Don't worry, it you read HFSJ and do some mock exam, you will passed.
Hello James !!!
I had 80 questions for the exams. I think any one who is taking the exam these days will have 80. Your score will be calculated on 69 questions. It means that there are 11 unscored questions on the exam. Personally, i think the exam is easier than
SCJP. After you read the book, do some
mock exam, you will be ok.
Hope it help. Good luck guys !!!
