@carrideen @sundogplanets This is very good advice. As a former director of a grad school program who has read many 1000's of recommendation letters, I'd like to add one addition: if the letter is for grad school applications, ask one professor writing you a letter to comment on your transcript in general. This is especially important for students who attended a smaller school where the admissions committee will not be familiar with the courses and the grading tendency of the faculty.
