today i passed with 76%. 70% was minimum, out of 87 questions.
1. ~5 questions are about security - HttpServletRequest + web.xml configuration
2. ~10 questions about composite components
3. 2 questions about custom components, without taglib descriptors
4. ~6 non-trivial facelets templating questions
5. ~4 questions about packaging JSF application, including taglib descriptors in WEB-INF
6. 10-15 questions about converters and validators - all you can think of
7. ~4 questions about GET requests (viewParams, h:link, h
8. ~5 questions about navigation, simple and bit harder ones
10. One question about PhaseListener, one about <h:graphicImage>, one exclusively about @Inject (WTF?), one about ui:debug
11. Few about Locale, some combined inside questions about converters
12. 10,15,20 questions "What is best practice" or "What scope would you use" - not that easy!
13. ~5 questions about actionListeners
14. 0 (zero) questions about ManagedProperty and ViewScope
15. 3 questions about datatables
16. few questions about <h:selectOneMenu> and <h:selectManyMenu>
17. few questions about lifecycle - "in what phase would you do this", "what phases are skipped if you do this" etc.
18. There were no questions about JSF 2.2 stuff (flowscope, statless view, HTML5 passthrough etc.)
At least half questions were verbose. I tried to follow advise from some people here who said, read answers first - it didn't help me much, maybe with 1 or 2 questions.
With few questions, i didn't realy understand what they wanted to ask, to be honest.
I learned from Core JSF, Java EE6 tutorial, BalusC @ stackoverflow + blog, and JSF 2.0 specification.
