Two weeks ago, I emailed my professor and requested he fill out a recommendation questionnaire for me (it’s not a letter, but what it is isn’t really important).
I haven’t received an email back and time is ticking. Would it be wrong if I went on to the next professor on my list?
I would email the other one – but also check with your first professor – it could just be that he missed the email and is preoccupied. Professors get alot of emails.
