Here are some of the best Mock Exams Available:

Marcus Green's Mock Exam 1
Marcus Green has composed 3 Mock exams in .html format. The exams are often in Javaranch's Programmer Certification Forum. Marcus frequents such conversations and respects users' comments, and if there is any ambiguity felt by many people , he changes the wording of those questions promptly. So the mock exams are refined by now and considered to be very good and their level of difficulty is close to the real exam. It is good if we get atleast 90 to 95% in all the 3 exams to get a high score in Sun's SCJP2 Exam. Many people said the first time when we take Marcus's sample test, the % we get is close to the % we get from the real Exam. So save them for the last 3 weeks of your real exam and see your % on them.
