A master's program that I want to apply to is asking for two letters of recommendation. I can get one of them, because I am very close with a professor that I'm doing a research project for, and I'm doing a good job in it.
But the second letter might be a problem. Basically, I have other professors and instructors to choose from, but none of them know me as well as the professor mentioned above. In their classes, I did well, but I wasn't top of the class.
There is one lab instructor that I had, and I always did very well in his lab (I'm good with hands-on work), but I don't know if he remembers me. He would always give me a bunch of extra credit for the lab reports.
Another professor I was thinking of asking is a statistics professor. I'm thinking he might be willing because at the beginning of his class, I was struggling, and failed the first midterm, but I studied and improved greatly in the end. I finished that class with a 3.5.
So my question is, how can you ask for a recommendation letter from a professor that doesn't know you all that well? I've seen others do it, but it always seems like they are the students who either did very well in their classes, or who have a much closer relationship with the professor.
Also, I'm on a time limit, as the masters application is due in about one month.
Any help would be appreciated. Thanks!
