<p>I’m currently doing my third SURF at Caltech this summer. It’s definitely 10 weeks and $6000. Also, I clicked CalAlum’s link, and it says 10 weeks in multiple places, so I’m not sure where anyone read 8 weeks.</p>
<p>On a more relevant note, I wouldn’t make any choice between MIT and Caltech (research, undergrad, or otherwise) based on the pay rates of UROP vs SURF. Other factors are far more important. But I guess you didn’t technically ask that question.</p>
