I think your chances for Notre Dame are pretty good. With a 3.91 unweighted GPA it’s surprising your class rank is not a little higher. Not being catholic should not be a problem. Very well rounded EC’s (athletics, music, other clubs) but not a lot of leadership positions, D is a freshman at ND this year. An even stronger SAT score or essays that clearly communicate your love for ND would help. 2140 is a very good SAT score but the applicant pool to ND has crazy high ACT/SAT scores
