I'm applying for Mathematics MS degree and I have an issue with getting an recommendation letter from undergrad professors. I didn't plan to apply for grad school unitil recently and I was never a type of student who visits professors during office hour or get friendly with them. Fortunately, I know two professors that I've worked with during an internship and they are willing to write me the letters. But as most schools require three letters, I still have an issue.
I do have classes (semester-long) that I got good grade, but again, I've never talked to any of those professors. For now, it seems I have two scenarios.
- Get letter from someone from non-academic field that knows me personally
- Get letter from undergrad professor who doesn't know me personally
I know it sounds ridiculous, but what would be the better choice?
