I've been accepted to both universities and just attended both of their admit weekends. I was selected as a Questbridge Match to Pton, and got into Stanford Regular Decision. However, I plan to attend Stanford now that I realize how strong their engineering program is (I plan to major in ChemE or EE). I haven't officially committed, but will soon...but I feel so bad declining Pton's QB Match offer after I emailed the admissions lady saying thank you and that I would attend...is this the right decision? I just have a gut feeling that Stanford is the right school for me...and not Pton. I just got an email from the regional admissions lady saying "hope to see you in the fall, we're excited for you to attend." Should I reply or ignore it?
