Try the exam guides from SYBEX or McGraw-Hill, they are not so expensive. You can "stick" your order to amazon with another friend that is paying the shipping costs. (Which I did... ). And you can order them USED, is really cheap. (Which I didn't, it was the anthrax time... )

I canot understand something. Is there any difference if you got the Oracle University instructor-led courses? Because I DID that, for 031,032,033! And I can tell you, the courses supports ARE NOT ENOUGH! They have some gaps, but at least the information that IS, is very precise and correct!
So, isn't the same exams 1z0-031, 032, 033??? What's the problem with the Oracle University courses?
