Hi Thomas,
Truthful answer regarding your accent was in the main it was perfectly good. At times you did seem to talk a bit too fast but that can be dealt with by having a more structured presentation. Not a problem today as you said it was mostly a test.
Some words or expressions I had to smile at. The alt key in particular.

I thought at first you were saying the L key. Nothing major at all really.
I learned a couple of things that I was only half aware of before, so it was a positive experience for me.
Cheers
