<p>I'm pretty sure that my teacher sent my recommendation like 2 weeks ago, but I received an email from Caltech telling me that my humanities recommendation is missing. So should I tell my teacher to send it again?</p>
<p>Doesn't Caltech allow you to fax the recommendation over to them?</p>
<p>I am pretty sure Caltech sent the emails after they had opened all received mail. So, yes, it does need to be sent again. How long do they give you? and do check if they will take faxes.</p>
