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 |
