It is quite often that I encounter attendees in my Oracle University courses that strive to become OCP or sometimes even OCM, asking me whether they should better go for an older versions certificate before they take on the most recent. The reasoning behind those questions is mostly that it may be easier to do it with the older version. My advise is then always: Go for the most recent version! No Oracle Certification exam is easy, but the older versions certificate is already outdated. The now most recent one will become outdated also sooner as you may think 🙂
For that reason I really appreciate the option to upgrade from 9i/10g/11g OCA directly to 12c OCP as discussed in this posting. There is just no point in becoming a new 11g OCP now when 12c is there, in my opinion. What do you think?
