Sorry for not responding sooner - I just noticed this
thread this morning. :-\ I took 310-056 about two weeks ago, and haven't really been paying as close attention in here as I could have been.... yeahwell.
Anyway.
What I found while studying for the exam is that there really isn't a lot of material that's out there for the upgrade specifically. What I could advise (I was upgrading, admittedly, from 1.2 to 5) is to concentrate on those new requirements in the
test objectives that were not on the 1.4 exam.
I did use a few books and websites (a brief look through HFJ 2nd edition, my Tiger developers' notebook, glances at online reviews of the JSE 5.0 objectives), but the lack of available material at the moment kind of shows in my poor showing on the exam - I passed, but not by much (hence why I didn't say anything in the results forum).
I've found that upgrades seem to be harder - at least to me - than the regular exams, if only because they concentrate on what's changed rather than giving you some of the easy questions you'd normally get with the unchanged areas included. Just make sure you're solid on your 1.4 items and move forward from there with the changed objectives.
