So I invited my teacher recommenders to the MIT recommendation site, ApplyWithUs, and I even have all the letters submitted. However, I learned that my school also sent the materials, including the secondary school report (but I’m not sure about one of the recommendations) through Naviance. So will everything eventually get matched up with my ApplyWithUs account anyways? Or is there something else I need to do to make sure all recommendations and the school report are together?
Yes. Admissions officers have done this drill before. You can be certain that they know how to match items together. Good luck.
