I would not even consider writing the Developer Exam without consulting this site on a regular basis. I agree that there is no better tool for sharping one's knowledge. However, as neccesary as this site is, I find books provide an equally important ingredient for preparing for the
test (especially for those of us who are relatively new to
Java), and that ingredient is structure. My
SCJP Exam books have been like a roadmap, while this site has helped me appreciate the view. If anyone could recommend a good road map to me, I would be grateful.
