from my experience with IBM exams you get a fairly good picture about them by looking at the questions of their ICE tool:
Someone has posted them here:
https://coderanch.com/t/144259/po/certification/IBM-ICE-TEST I have passed the previous 158 test. I found it really hard. Two people might find different things difficult, but I would say that this one contains more complex stuff than the WSAD-test.
just my 2 cents.
