MAT 145 Grade


To see your grade, compute the quantity called "L4" in the list by the following formula.

First, look at the last four digits of your Student ID Number. Let the number be N.

L4 is the last four digits of the binomial coefficient N choose 2.

(The original last four digits of the Student ID Number cannot be uniquely recovered from L4. The map we are using here is not one-to-one.)


Please notice that the HW column is the sum of your 7 best homework scores. Thus the full mark is 42.
