I'm always excited to see a new text on OCA/OCP
Java 7 exams. I'm interested in the difficulty of the sample exam questions. Relative to the sources most people recommend on this site (largely being Gupta, Enthuware, and the Oracle website), how do the exams in Sierra & Bates compare? Also, because Sierra & Bates covers both OCA and OCP, is one of the exams under focus more than the other? Thank you!
