thanks to everyone in SCDJWS cert. exam forum and result forum.
it took me about 6 weeks to prepare. RMH's book, Blueprint, JWSDP tutorial and MZ guide are more than enough.
I would say we don't need exam cram for this cert.
many security and JAXR questions were seen. Blueprint is a must-read for Architecture related questions. It may be difficult if you don't read Blueprint for design topics.
if you know the purpose and benefit of each Security terminology like SAML, it is enough for the Exam.
