My school puts together a composite letter of evaluation written by a panel of professors for each applicant. I also have at least two additional letters for my application. My question is this: How many letters is too many? I asked my advisor who said that I should avoid sending more than one additional letter. He said the adcoms don't want to read all day... I feel like omitting letters would hurt my application more than having too many. What do you think? I must decide soon, so any help is appreciated.
