Yesterday I've passed the
SCJP exam.
As preparation I used the K&B book,
Java Language Specification and Whizlabs. My whizlabs scores were 67%,68%,75%,70%,74%,82%. I found the real exam questions a bit easier. The Learnkey mock exams delivered with the K&B book I didn't use that much because I think it has a horrible user interface. The UI on the exam was much better. I didn't need scrolling for navigating the code or so.
I hope I'm better of now for my next job interview.
Thanks for the advice I've got from this site.
