Invigilating

"Invigilate" is still the strangest word for me (British term for proctoring exams). In any case, I try to keep hawk eyes on students and sketch discreetly at the same time. If I stand behind them, they can't see me.

This is red colored pencil on a small prepared page (3"x6", green watercolor wash). Then I used a Stabilo permanent pen for the text and cross-hatching. I have been paying attention to slowing down, which allows for more accuracy. And this student barely moved, but, stared a lot at the paper in front of him...
