The questions part comes from finding that to make up a good question, you must understand the material well and think about it. Some of the questions turned in are used on the quizzes and final. Thus a total of 360 points is possible. If everyone did so well that the distribution was very skewed toward the high end, the above would not apply. After the above distribution has been constructed and grade cutoff points assigned, the extra credit points will be added in for those that have contracted for them.
Some people can get higher grades by superior performance on tests alone.
Extra credit may now raise your grade after the basic distribution has been determined. Questions should deal with the current reading assignments and the previous week s lecture. At least one question in each set of four should be drawn from lectures. The contract system is an attempt to give more individual opportunity to students who want a higher grade and are willing to work for it. It s not perfect.
