Akash do a lot of reading from any book you get that will prepare you for the exam(K&B is the best you get). And along with that do a lots and lots of mocks that you can grab. Think about the knowledge you gain for the exam and not just the certificate that you get after passing the exam. Work hard and harder, I am sure you will do good.
Depending on which version of the exam you take, there are something like 35 or 37 objectives. You can expect each objective to get about the same amount of coverage, so basically you should plan on getting 2 questions per objective. That will seldom be exactly true, but it's a good approximation.
