Is it ok to receive no feedback in this situation in Coursework, Advising, and Exams Posted June 13 How many days? It is not uncommon for my supervisor to get my feedback months later, depending on how many other projects they have in the works. Next time you send something for feedback, I would say something like, "I'd like to get this submitted by July 31. Does that timeline work for you?" As far as emailing about the brief idea, my supervisor doesn't seem to respond to things like that either. They have to decide how much guidance to give you and it sounds like they trust you to integrate the new idea or not.
