First of all I would like to thank you all...
@dhwani mathur
In India the voucher you can get from some particular NIIT offices ...
Now a offer is going on, you can get the voucher @only Rs. 4500... This will valid up to 30 March... The original price in India is Rs. 7200
For the Exam I can say first you have to clear the concept.
You should visualize the whole thing... If you dont have any exp on JSP and Servlet then practice a lot... Go through the book again and again...
Before you sleep just recall the things what you read that day...
When you realize that you got the whole concept, then start to solve the questions after each chapter.
When you complete the whole task... Start to take free Mock exams...
Then You can go for Enthuwere Mock Kit if you want...
Lastly Go through the mock exams of Head First...
All the chapters are equally important for the exam and the real world application... Prepare all the possible APIs, classes, Interfaces, web.xml and tld very well...
I think this will help you...
Wish You All the best!!!
