I'm curretly reading the Oracle 10G exam guide preparation book from Oracle Press. I would like to know whether Oracle Press book or Sybex is ideal from the exam point of view. Which one prepares you well for the exams?.
I will tell you that OraclePress is notorious for errors in the print. However, the explanations are a little more thorough. Sybex books are a better value since the disc included has an electronic version of the book and several practice exams. The topics are all covered in Sybex but I felt that they were very short explanations. Sybex uses a seed database in Oracle to guide you better than OraclePress does. Dollar for Dollar, I would highly recommend Sybex over OraclePress. Try buying the SelfTest Software. Oracle recommends it and the practice tests mimic the real exam to a tee!
