Today, I finished in Munich the two days OCM Exam. That was really hard work! Nobody should underestimate the requirements in form of knowledge and experience for that hands on exam.
If you look at the topics, presented here and you can honestly say: “I am familiar with this stuff.”, then go for it. Otherwise practice and practice and repeat that until you can. 🙂
Well, I am quite confident that I passed the exam, but it was not easy – although I am teaching most of the Oracle University courses, it is built upon.
