Final class grades: The first column lists the last four digits of your Columbia ID number (C00...), sometimes called a PID, not not your social security number. You can find your PID at Student Services On-line. For Barnard students, it contains the last four digits of your seven-digit student ID number.

The grading scale is as follows:
Grade points >=
D 38
D+ 42
C- 46
C 50
C+ 54
B- 58
B 62
B+ 66
A- 70
A 74
