We are a small school with relatively small classes.  My exams (for any course/level) typically contain at most 10 multiple choice questions.  However, we are now administering the ACS exams as final exams for many of our courses.  Since I started, we have always graded these by hand using self-generated answer sheets where students write in their choice (no bubble filling).  For multiple reasons, we think we need a more efficient (and accurate) system.
