Best of luck!
If you are using the first edition of Head First
Servlets and
JSP, I recommend taking lots of practice exams from lots of different sources. The first edition of the book covered about 90% of the questions I encountered, so taking many
test can help bridge the gap. I took the
Java Ranch exam, the Marcus Green exams, and the one in my book. It wasn't quite enough to get the score I wanted, but I did pass.
