Hi Earle:
This is a good idea. A variation is to incorporate several methods of assessment in one test, such as multiple choice portion, essay portion, matching portion, true and false portion, labeling portion, worked problem portion, and so on. By adding some variety, it gives more opportunities for studnts to demonstrate what they've learned. All evaluations should ccurately measure the degree to which the student has learned and met the course learning objectives.
