I have previously used WEBWORK only for homework, but now need testing.
I have set up several short/experimental gateway quizzes @ 3-4 problems, all of those being problems that previously worked fine in homework assignments.
It seems that:
a) for some problems, webwork will neither preview nor store an answer. When hitting “preview” the answer disappears and a new version of the problem comes up
b) for some problems, webwork will preview and record an answer AND then show that answer as CORRECT when the student hits “grade” but the point(s) for that problem are not included in the test total score
c) for some problem, the preview and scoring work correctly
Nothing obvious jumps out for me when looking at the documentation
