I had a good time durring this course as I got a chance to pass my knowledge to others. I didn't get the courses evaluation yet but I guess I taught them good ;).
Some of them was part of the same group I taught IUT230 Billing and Invocing for 4 days in April.
Here are some pictures.

Later Edit: WOW! I got 6.9 in the instructor evaluation. Thank you guys, it is really great you enjoyed it so much!
