I'm applying to the MTS at Notre Dame this season, and would appreciate any advice that successful past applicants might be willing to share. I'm particularly concerned about GPA. I finished my BA at an Ivy with a 3.48 cumulative GPA. The rest of my application -- personal statement, letters of rec, curriculum vitae, writing sample, GRE -- should be excellent, but I'm just worried about the GPA since I've heard that MTS admissions are extremely competitive. Advice would be much appreciated.
