Material was well planned and examples used simplified concepts. Unfortunately I was pressed for time so didn't get to explore all the additional features available but I would highly recommend program to others.

Good and excellent support. Good prices for the modules and trainings. And also those courses can be claimed as PDU, which is great for me.
