Thanks once again to the good people here at javaranch... your tips and discussion helped greatly!
What I did to prepare: I started with the More Servlets book by Marty Hall, studying sort of part time, maybe 6 hours a week. Also I set up Tomcat 4 and played with the concepts.
About 2 or 3 weeks ago I kicked it into high gear - bought the ebook version of "SCWCD Exam Study Kit" by Hanumant Deshmukh (www.manning.com) and went through every chapter in great detail. I tried all the example code, did all the review questions at the end of each chapter, and finally took the 3 practice test in the included JWeb+ that comes with the book.
The SCWCD Exam Study kit is an *excellent* book to study from, very well written and presented. The JWeb+ practice tests were slightly easier than the actual test, but they are good to glue the concepts into your brain. It also includes a "last minute" Exam Quick Prep which I printed and reviewed in the car outside the testing center!
Thanks again to all; good luck to those persuing the SCWCD!
