The NumWorks graphing calculator

Your PE class consisted of world-class runners? Anyways, while the best of the best may be close, it does not imply that their respective bell curves align. Or were the goal times very disparate for the distance?

Anyways, that sounds odd. I feel that we'd do it more by effort in the US. I can walk a 12 minute mile, but others can't even run that (for various reasons). I do not deserve the same grade for slacking off if they're giving it their all to get the same time. There are benchmarks for special mention, but I believe those are set up at some percentile of times across the nation (per sex) and are more descriptive than prescriptive.

How did your grading system deal with handicaps such as crutches (temporary injuries), wheelchairs (for longer-term afflictions), and the like?
