Be able to in a grade-inflated major or in a very rigorous program?
Doesn't matter. Admissions counselors tend to adjust based on major and university. A 3.2 in mechanical engineering at MIT is higher than a 3.8 in business admin at Joeblow Tech.
For law school admissions?? Nuh uh. Come on. Look at LSN. It matters some, but not to the extent that a 3.2 would trump a 3.8, no matter what the respective programs.
I don't find this line of inquiry very interesting, so I'll let it be, but that part is just not true.
Is LSN completely reliable. I tend to agree that a lower GPA in a super-tough major from a more competitive school should and does trump a higher GPA in a more relaxed major from a so-so school. Law school dean's admit that they will give more rope to a lower GPA if the major and school are tough. But the interpretations of those relative strengths make the science so inexact.
