How sweet of you to be concerned on other’s behalf. I don’t think you have to worry on Brown’s account though. Students there do very well in grad school results. I know many of my daughter’s friends did, and she had top 10 results too in CS PHD program acceptance. It is not true that there are no requirements. Majors have comprehensive requirements similar to any other top rigorous school. Yes you can drop classes, however graduation rates remains high for the 4 year and the 6 year assessments. And you can do pass/fail, yes, mine did that with two courses, Mandarin and Russian. Oh and fiction writing which was mandatory. I guess you would have to ask grad schools how they compare gpa but they are even more interested in the research experience the candidate has which is has a high participation rate at Brown.
At least Brown is not ‘the laughing stock of the Ivy League’ as that honor goes to Harvard.
