I am applying for PhD in engineering and wondering whether should I take recommendation letter from academic advisor during master's program.
He has 'professor' in his title. He was not my thesis advisor and I did not take any courses from him. His role was more like advising students which courses to take, approving their courses for the semester, judging whether a student meet with course requirements, etc.
This recommendation letter would be based on generalization, such as GPA. I know a recommendation letter should be specific, but can a letter from such professor help or harm?
