For people who are preparing for the exam, the Marcus Green practice tests are definitely the closest to the actual exam I found. I took test 2 (and didn't count the questions that were in the 1.2 exam) the night before the test and scored a 88%, spend a little more time studying, and ended up with my 93% on the actual exam.
I did not so hot on the garbage collection area -- only 1 out of the 3 questions. Then I got 87% on the Threads section and an 83% on the Overloading, Overriding, Runtime, Type and object Orientation section. The rest I got 100% in.
Thanks Bert and Marcus! Bert, I thoroughly enjoyed yours and Kathy's book -- not only was I learning, but I was entertained! It kept me wanting to read more. Marcus, your site helped a lot while I was studying for the exam! Thanks a bunch!
