I just attempted to build my first test with SG and had a couple of suggestions:

1. The question point input field would not allow percentages, only whole numbers. I was trying to assign 1.3 points per question, but the program would not take them.

2. It would be very nice if a student taking the test could see the score upon completion of the test.

It's possible that these two suggestions above are available and I just missed them, but if they are not current features, they should be added as they would certainly enhance the program's usefulness.
