Together with Matthias Merz we created Seam – Basic Exam at JavaBlackBelt.
It verifies general understanding of the Seam 2.0 concepts, required to implement a simple Seam application.
The exam is now in the beta stage, which means it is available publicly and you can take the (beta) exam, which does not count for your belt progress. It will be released as soon as we collect enough stable questions in each category.
Like all exams available at JavaBlackBelt, it is free.
You are welcome to contribute your own questions and improve or rate existing ones.
Cheers,
-Pawel
