The "raw score" is the percent of correct answers on an individual assignment. To produce the "curved score" for that assignment, raw scores are adjusted so that the class median is 85 and the maximum is 100. Then the student gets the maximum of the raw and curved scores. Thus, the curve never reduces a student's score.
For each student, the curved scores of the various assignments are averaged to get the final score. We assign letter grades subjectively, based on these final scores.
