My daughter also received a Presidential Scholarship offer and nearly chose Clark. I don’t agree that it has a poor vibe: we loved the students we met there, all of whom seemed passionate about their school and their studies and seemed engaged with the community around them. Clark has an emphasis on global affairs and international engagement as well, and is offering you special opportunities. Clark is closer to Boston than Lafayette is to New York. You don’t even mention Philadelphia. My sense is you haven’t really done your homework and are acting on stereotypes. If you are going to come to the US to attend college, consider that you need to be open to a broader notion of what your education can offer you and shed your narrow notions of what will add to your “prestige,” e.g., being a “scholar” and not a “normal student.” The normal students will be your peers, not for you to look down on as “not smart” etc. Adjust your attitude before choosing a school or you will likely be disappointed with either choice. This recent article about Worcester may be of interest as well:
