I passed the SCWCD exam this morning and scored 84%. It's a nice score for me, since I did not have any real experience with JSP and tags.
Prepared using the Head-First book. Read it once and some parts twice. Then I made the Whizlabs exams, scoring 80% at the end. Then I tried the Enthuware software in which I consistently passed all 7 exams (be it barely in some cases, scoring 75% at max).
Total preparation time was 3 weeks.
Thanks all for your help. Now it's on to SCJD and SCBCD!
