No late homework is accepted. Homework will be graded on the basis of 10 points per assignment, and scores will be recorded. Homework and performance on the final exam are important in influencing borderline decisions. Standard scores are computed by subtracting the class mean from your raw score, dividing this difference by the standard deviation, multiplying by ten, and adding 50. The result is a set of scores which have a mean of 50 and a standard deviation of 10.
Standardized scores take into account the relative difficulty of each exam.
Intuitively, a high raw score on a hard exam should count more than the same high raw score on an easy exam. Standard scores make this happen. It is also easier to interpret standard scores. Initial letter grades are separated by 10 points or one standard deviation. Thus if your standard score improves by 10 points, you have improved by approximately one letter grade.
