Basically I was wondering if I could get some more information regarding PS prompts. I bought a Personal Statement review and the guy that looked at it pointed out to me that I might have to write two (or even three) different Personal statements. This came up since he informed me that most of the schools I'm applying to (BU, BC, FIU) all make the mention of wanting to know, basically, why I want to study law. This seems in direct contrast to most of the PS writing advice I've researched so far. Obviously the prompt is the cause of this change, so I'm just wondering if anybody can share some thoughts about this sort of "different ballgame" that I find myself in now. Maybe there is a blog/article that can expand on this issue? Just because I'm feeling a bit disenchanted since I thought I had a pretty good grasp of the Personal Statement.
Also, is there a lot of weight attributed to the personal statement prompt by the university? Or is it more of a light suggestion kind of thing?
Thanks!
