I bought OCP test kit from ucertify and got 50% discount, its absolutely a fair deal. But buddy, I should tell you that I am very much impressed with their test engine. It was difficult for me to get used to to their navigation. But, when I starting using it, I found it very informative. This is my first purchase from ucertify.com. For books i looked Oracle Press (Osborne/McGraw-Hill), Oracle bookshop(online book shop). I think this is sufficent. A lot to study but not difficult if you cover all the areas. Less time i have, time is running out for me.
