For me, it is clear from the Sun web site that you will get a smaller selection of questions from the normal
SCJP 5.0 examination. All irrelevant questions (e.g. Math class, shift operators) from SCJP 1.4 have already been removed from SCJP 5.0. Those questions on topics from SCJP 1.4 that remain in SCJP 5.0 have been mostly rewritten to enhance the understanding aspect rather than the rote memory aspect common to the earlier examinations. So no shortcuts.
