Currently, I have four letters (2 PI, 2 professor). The 2 PI letters are extremely strong, but I am now having concerns about the professor letter from a high-level math course I took. I had a great working relationship with him, and he told me I was a top student in the course, and he was happy to write me the letter. However, I am worried that the conventions for letters of rec may be different for med school compared to what he normally writes (his field is computational math), and could potentially include a weakness or not be "glowing." I would not be surprised if I'm the first student he's ever had to write a medical school recommendation letter for. I've heard of some letter writers offering a "balanced" perspective rather than effusive praise, and I could see him doing this. I can't think of any reason I've given him to include a weakness, but is it fair to be concerned about a non-exceptional letter from him simply due to his field?
For context, I am applying to many T20s because I am a high-stat applicant, and leaving his letter out would leave me with 3 strong letters - it fits the minimum at many schools, but is this enough to be competitive for top schools?
