I haven’t even started on Sam Alapati’s OCP book but I realized today that Matthew Morris’s OCP 12c upgrade book has an outline of the Key DBA Skills section of the OCP exam and that is what I need most. I was two questions away on that section when I took the test the first time and I need to make sure I’m studying the right things. After I got back to the office after failing my first attempt (a $245 lesson) I made notes about what I remember being unsure of and that gave me some ideas what to study. But, it is nice to get some advice from someone else who has passed the exam. I saved a couple of bucks by getting the Kindle version for $9.99 so it seemed like a safe bet. Hopefully I can hit it hard on both books and my practice test software, which also covers the key DBA skills, and be able to take the test again by the end of the August.
