I would like to ask Oracle gurus here regarding to the preparation meterial for Oracle OCA exam 1Z0-007.
I saw two choices on the market:
1)OCP Introduction to Oracle9i: SQL Exam Guide by Jason Couchman
2) OCA/OCP: Introduction to Oracle9i SQL Study Guide by Chip Dawes, Biju Thomas
Which one is better and worth buying for the purpose of passing the exam?
