Hi, I'm currently certified with
SCJP 1.4, which I aquired a long time back and thought it was a good time to upgrade. I originally bought Jeanne and Scotts OCA Study Guide book and planned to sit for the 1Z0-808 exam. I was then going to purchase the OCP book and sit for the 1Z0-809 exam.
I just realised there is the upgrade exam 1Z0-813 that I can sit instead. I've read through the OCA prep book once already, but wonder if there is any need to keep studying the OCA exam book, or should I just get the new OCP book and study that instead? Does the OCP book cover everything I need to know for the 1Z0-813 upgrade exam?
