Hi Anna: Good, nobody wants surprises at the end of the course. It's interesting that I sense some instructors challenge their students (in testing) in a way that makes it extremely difficult to earn top grades - almost like "I dare you". Don't understand. As facilitators, we are collaborators with our students, sharing, teaching, simplifying - taking the time to attain understanding. There's an old saying 90% of your students should 90% or better. It's not scientific, but seems like a terrific goal to shoot for. Certainly, frequent and early on encoragement and support along with advice and suggestions will assist making a difference in the final grades as there is enough time for correction. Regards, Barry
