<p>Some schools I am applying to require a recommendation from either a math or science teacher. I've been taking math at a CC since sophomore year, so I was going to ask a professor that I had last semester; although I only had him for a semester, I feel that he knows me well--however, I'm not sure if his letter would count as one of my teacher recs or a supplementary one because he doesn't teach at my high school. Should I add him as a teacher on my commonapp, or have him as my "additional letter"? I know that the colleges wouldn't appreciate extra letters when not asked for....so help please?</p>
