<p>Excellent! One thing though – it’s not an “adcom” that you need to impress. Graduate admissions is very different from undergraduate admissions; particularly, it will not be a detached committee reviewing your application but rather the research professors and department chairs in Mathematics at each of the Unis you’re applying to. If you pulled 3.6+'s in MVC, complex analysis, partial diff eq, etc., then none of the Dept Chairs will care that you got a “W” in Women’s Studies or Calc I. </p>
<p>The three-year-in-the-making thesis sounds very impressive. That, along with a glowing rec letter, could easily get you into Dartmouth/ND/FSU/wherever. Best of luck! :)</p>
