This morning I passed the upgrade from SCWCD 1.4 to 5.
The
test was 50 questions in 2 1.2 hours, more that enough time.
More design
patterns than I expected (10-15%). Also deployment descriptors and EL were emphasized.
I mostly used "HFSJ 2nd ed", "SCWCD Study Companion" by Lyons, and Marcus Greens' web site.
If you have the time to read both books, I suggest HFSJ first and Lyons second. I found HFSJ is good at getting the basic ideas, and then I had enough context to hang the details in Lyons.
