Summer programs

<p>Do colleges really look that one has taken a summer program? I've been offered to take an accelerated chemistry lab course this summer, would this help significantly? I could do some biology research as well, which because I'm going to major in bio it would probably be good, but honestly my courses this past year have completely stressed me out. Would taking it easy the entire summer to destress be devastating to college addmissions or not? Or should I do some courses/research this summer?</p>
