Discussion on question by Luna: How to respond to a student email demanding quick feedback?

His e-mail is not really demanding after all. Except for the word "promptly", which is indeed inappropriate in this context, "Please let me know" is a reasonably polite request. If the student is not a native speaker, he or she might not feel the difference between "promptly" and "whenever it is possible for you". You can't expect that they know the email etiquette right from the start. Where would they have the opportunity to learn it The student might have missed your announcement about 2 weeks, which also happens often.

@SemidiurnalSimon Whenever I teach students the course is structured such that they have feedback, a tutorial, and an opportunity to ask questions in the office hours, before they have to do the next assignment. I realize that the above essays are probably not related to mathematics/computer science, but writing the second essay with no feedback still sounds suboptimal. That said, the question isn't really about that.
