Of the 11 universities on my list, Carnegie Mellon is by far the university that had its application portal open last. I could even complete all the other ten forms (and Vinet could even write these ten LORs) before I got to even open my application at Carnegie Mellon. I even sent the supporting materials before the portal opened.
Because it takes time for recommenders to write the letters, and that CMU sends out prompts for the LORs only after the actual application is submitted, I find it regrettable that they had to wait until today for the portal to open. Even UPenn, with its portal being accessible by october 1, was not overly late.
Now, for more news concerning the paperwork. UChicago and Tufts have both verified my GRE and TOEFL scores, so at least I know they have received the scores. However, WUSTL, Columbia are a little slower to process the scores.
