<p>I would like to know how many letters of recommendation CMU would prefer to see for my application to SCS? Would sending two-three teacher letters be on average with other applicants?</p>
<p>Yeah, two-three seems to be about on par. If I recall correctly, I only submitted 2. Submitting any more than 3 is massive overkill - I don’t think most adcoms even read the letters unless you’re an “on the fence” applicant.</p>
