Hi Tom, like Nate said, for your first exam you don't really have a choice. It is the SCJP. With your experience, I'd suggest getting The RHE book at
Complete Java Certification Study Guide by RHE.
And I think one read through and answers some of their questions, and also doing a bunch of Mocks you will be ready in under a month.
But the best resource is to go to the SJCP forum.
Then when you compelte that one join us here at
SCJD forum, or you can go to SCWCD ecert Forum. If you have done
JSP and
Servlets in your experience, then your step after SCJP should be SCWCD and you cna compelte that pretty quickly too. Then come back to SCJD.
Good Luck and see you soon.
Mark
