Hi Nilesh,
From now on, I think
you should relax and concentrate your efforts in order to review your notes with key points for the exam.
You have to agree with me that if you are not prepared for the exam by now, one week for sure is not enough to learn everything, so be confident, everything you need to know you have learnt in the past weeks.
I think the key point is : If you are consistent in the mock exams you write (by scoring 80% or more), I think you can go for the exam certain that you will pass.
During the next days before the exam, try to answers ALL questions posted on JavaRanch and read other replies in order to detect wrong answers and fix them.
On the day before the exam, forget JavaRanch, forget books, forget
Java, forget everything !!!. Try to relax, watch a good movie, play some good game and then have a good night sleep.
For sure you can pass !
Good luck man !
Hope to see you in SCWCD forum.
