Yeah - I just passed the Flex 4 ACE Exam which is mandatory to keep my Adobe Certified Instructor (ACI) status for teaching the official Adobe Flex courseware.

It was the third time that I took a Flex exam (first one was about Flex 2) but still it's a moment of great suspense when I click on the final "End exam" button to end the test and get the results (it's a sort of online test which has to be taken at a test center)

This time I passed with 84% which means 50 out of the 59 questions were correct. Unfortunately they don't show you the wrong answers afterwards which would be very interesting.

If you want to certify as well make sure to take a look at the Spark architecture, Service integration (including LCDS and Model Driven Development) and general OOP topics with focus on ActionScript implementation details. And if you're a Flex veteran (like me) with a strong Flex 3 background make sure to take an extra deep look at the at the Spark architecture :)

Thanks!

actually, I looked up a lot of the "basic" things in the Flex product documentation (focusing on Spark layouts and the skinning architecture) and also focused on specific AIR APIs (e.g. File API, SQLite API, etc.) which was a good decision.

To get a feeling for the type of questions I recommend you to check out Attest 3 (http://software.pxldesigns.com/attest3/)

In essence: when you're using Flex 4 on a daily basis and have 1+ years of experience in using it, it shouldn't be a problem.
