<p>Can you just e-mail the profs and ask if you can work in a lab anytime during the school year, or does it have to be during the first week of school or maybe even before the school season begins?</p>
<p>You can do it any time. Often you have the choice of working for credits or pay. I imagine if you’re picking it up mid-semester you’d probably get paid, but you could then switch to credit for the following semester.</p>
