<p>I think I already made my opinion pretty clear.</p>
<p>And I still wonder what OP was thinking. </p>
<p>I don’t think your friend has a realistic chance no matter what, but I can only imagine this letter hurting rather than helping. And it may make them re-think your probable admission and your judgment. I’d let it go. But bonus points to you for being a caring friend.</p>
<p>I think an unsolicited peer recommendation MIGHT help if an applicant is overwhelmingly academically qualified, but suspect with regard to social and interpersonal skills. For example, a committee might wonder about a kid with perfect test scores, an impressive transcript and, say, a high proficiency in five or six programing languages, but no team sports or group activities. Will that kid venture outside his dorm room? A well written peer letter might help with that concern. </p>
<p>@Arwarw, the college counselor rec should address that if necessary. </p>
<p>I suspect that the real truth is that an unsolicited peer recommendation would do neither harm nor good unless it was highly unusual in some respect.</p>
