You have 2 possible paths to choose from:
take (and pass) the Upgrade to Java SE 7 Programmer (1Z0-805) examtake (and pass) both the OCAJP7 and OCPJP7 exams

Since Java 7, Oracle has split the certification in 2 parts: the OCA one is the entry-level exam and covers java and OO basics. The OCP is the more advanced exam and covers a lot of advanced topics (generics, threads, concurrency,
jdbc, file i/o, nio2.0,...). No need to take (and pay) for both exams, you can simply
upgrade your certification by taking the 1Z0-805 Upgrade exam.

Yes, if you completely read the K&B7 study guide and have a good understanding of all concepts and topics explained; you'll definitely pass the 1Z0-805 Upgrade exam and reach your goal of becoming Java 7 certified. Good luck!
Hope it helps!
