If anyone struggles with the demand for instant feedback I recommend using an online grade portal so the students can login and see their overall and individual assignment grades anytime. Even if your school does not provide this feature, there are some great websites like www.engrade.com. Engrade has really improved relations between my feedback-demanding students and I. They used to come ask me every single day (unable to wait for a weekly progress report), now they have access anytime and we only have to discuss it if they feel there is a discrepancy.
