Hi,
Having searched through a long list of mocks and example questions, I found many weren't very good, contained wrong answers or were just too old. So I thought I'd share with you a short list of the ones I think are worth doing;
1) John Meyer's Exam
http://enigma.vm.bytemark.co.uk/webstart.html 2) MasterExams CD Mocks that come with the
SCJP book by KS & BB
3) The questions in the SCJP book by KS & BB
4) The questions available on the sun website.
Cheers,
Mike
