<p>Here's the problem - I've already sent two recommendations by mail to all the colleges I plan on applying to. I haven't read either of them; however, I have reason to believe that one of these recommendations may portray me in a negative light. Since some colleges only require one recommendation, is it possible to not use this recommendation by not entering the teacher in these colleges' School Forms section on the Common Application? Or will colleges look at everything they received by mail?</p>
