Here are actually the attrituion numbers:
After 1st year: Academic (63), Other (58) for a total of 121
2nd year: Academic (16), Other (17), for a total of 33
3rd year: Academic (2), Other (0), for a total of 2
By the end of law school, your class will likely have lost at least 150 people.
My point is that you shouldn't have needed to be affirmatively WARNED by somebody. You should have known those numbers before you ever went there.
