That should be enough to pass the exam. If you are still in doubt you can purchase the Enthuware mock exams. These exams are great value for money.

Just study the exam objectives. Enums, wrapper classes & inner classes are definitely not on the OCAJP7 exam! A little note about the wrapper classes: although they are not in the exam objectives, some people already mentioned they got a question with a wrapper class in it, but the question didn't require knowledge about wrapper classes to answer the question correctly.

Have a look
here. This
thread contains a bunch of user experiences about the exam.
Hope it helps!
Kind regards,
