<p>A rec from a Stanford prof can be a great boost, or can be nothing at all - it all depends what is in that rec. More importantly, there is nothing you can do about it. Just work on your own application, and make it the best you can - don't try to outdo you friend.</p>
<p>"Please remember that a letter from a famous person or Stanford alumnus is not going to help us reach a decision if that person is unable to add new insights to your application."</p>
