Last Friday, I took the SCWCD exam and passed with 88%.
Study material I used:
* HFSJ - Did about 2 weeks to read this book twice.
* Whizlab mock exams - Played with it for about 1 week
* Whizlab quick revision notes - As it says, very helpful for reviewing just before the exam
In addition to HFSJ you should have a look at the Servlet, JSP and JSTL specs because some details are not mentioned in the book. If you want a perfect score the way to go...
Thanks to all the Java rancher's to keep this forum up. Your questions and answers have been very helpful.
