I like John Kulig's suggestions. In fact, I do them all. As for the problem
with runs of the same answer over several questions, having too many of one
answer, etc., this is what I do: As I write test questions, the first will
have A as the correct answer, the second will have B, the third will have
C, and the last will have D. I then start over again with A. When I am
done, I randomize the order when I print the test (by hitting the
random-sequence key). This way I have an equal number of each answer on the
final test, and they are in a random order (according to the randomization
function of the testing program). Of course, this doesn't work if you use
test-bank questions provided by the publisher. But I don't like these test
banks, so I usually write my own MC questions.
