Which study guides should I use in order to pass the 1Z0-822 exam?
"Should I buy ""OCA/OCP Java SE 7 Programmer I & II Study Guide"" (Kathy Sierra, Bert Bates) if I already have ""Sun Certified Programmer for Java 6 Study Guide"" (Kathy Sierra, Bert Bates) to prepare for the ""Java SE 7 Programmer I 1Z0-803"" exam?"
