Well, Buying a collection is always useful and result is fruitful. I have made 3 test collections for oracle and got total of 30% discounts on collection and there are now 70% discount, but i bought it before. I know the real exam is so much difficult. You should have the knowledge about whole exam topics. I had downloaded materials from net. Even you don't need to go any vendor and purchase anything. Free materials are enough on net. Net is the best friend of yours.
