Yes, I agree that either or both would be good preparation for law school. Is that what this student is saying?
If that’s not the goal, then we’re looking at humanities on the one hand vs social science on the other. While either are good general preparation for a wide variety of career paths, they do have different implications for a student’s interests and different options when we ignore the future options where they do overlap.
I’d just like to get clear about what this student’s are that led to these 2 choices.
