I am currently applying to graduate school and trying to gather some solid letters of recommendation.
During my undergraduate studies, I worked in a research lab and while I didn't get that close with the professor, I decided to take a shot and ask her for a letter of recommendation. I sent an email two weeks ago and she has not responded. How long should I wait before emailing again? How do I ask again without being pushy? My fear is that she barely remembers me and this is her way of saying no. Should I just ask someone else?
