So far, I have taken the following mocks: MasterExam, Marcus Green, Voodoo, Whizlab Demo, Sun Demo, Dan Chisholm, Tests in the Sierra/Bates book (SCJP & SCJD Study Guide).
I didn't buy Whizlabs. I don't want to spend money when there are so many free mocks.
My scores vary depending on the mocks:
MasterExam (2 exams): 90% Marcus Green: 90% Voodoo Mocks: 85% Dan Chisholm Exams: 85%, depends on topic, I got destroyed on "Wrappers", very hard exam Whizlab Demo: 55% (ran out of time) Sun Demo: 90% Sierra/Bates from book: 93%
Don't be shy...let's here about your mock experiences!! [ July 23, 2006: Message edited by: Douglas Chorpita ]
I'll have to say that the Whizlabs and JQ++ mock exams are sufficient. They contain around 13 mocks each, all of which are well done. I haven't tried the free ones though, with the exception of Voodoo.
