It is possible to use a cutoff that is greater or lower than 0.5. In general, lowering the cutoff value will result in a decrease (no change) in the classification error rate for records that are truly C1. Note that is not an overall error rate. True False

A student can register classes of his/her choosing during the registration period. If the system found there are pre-requisite violations the student will be de- registered from the violating classes. A student who was de-registered up to three times will be warned.
