I am trying to use pc_evaluator to give partial credit for some answers and full credit for the correct answer with a message when the student gets partial credit as to what they should have done. The problem is that partial credit is assigned correctly but when one sees the "correct answer" when soultions are available, it is always keyed to the one for which some partial credit is given. From a student's viewpoint, it may seem to them that they actually have the correct answer but incorrect credit was given to them. Am I using pc-evalulator incorrectly or is there some way to work around this...other than of course explaining this to them in a written solution that what they are seeing an incorrect naswer in the correct answer box and giving them the correct answer.
