i posted a question about this a couple of months ago, but got no response, so i'm trying again. i went to undergrad at a university that gave you the option of selecting letter grades or a pass/no pass option in all of your classes. if you wanted to have a gpa, you had to take at lease 2/3 of your classes for letter grades, which i did. lsac does not factor any of the classes i took for the pass/no pass option in my gpa, nor do they include those classes when they list my cumulative semester hours. so, it looks like i took a lot fewer classes than most people normally would to obtain a degree. also, many of these classes were upper division. should i write an addendum explaining the grading policies at my undergrad, or do you think law schools are already aware? lsac has enough data from my school to show the percentage distribution of lsat and gpa, so obviously folks that went there have applied to law schools before. any advice is greatly appreciated!
