Fun, thank you! The SE gave me some trouble, partly because of the 25D that @SporcleMirror mentioned. As I understand it, ALUMNA is singular and feminine, while "grads" implies plural — which would either be ALUMNI (which is the right length) for masculine (which is also used for mixed gender) or ALUMNAE for feminine. Also, Wesleyan has been co-educational for years (1970s?) so it was more challenging (this didn't make it wrong of course).
