Just wanted to mention, if you have heard nothing at all from those schools I really recommend double checking with the department that everything is okay with your application. I applied to both cu-boulder and Michigan, and they both lost my app/had it stuck in administrative limbo. If I hadn't contacted Michigan, I'm not sure I would've ever heard back -- thankfully got in, but I'm still stuck in limbo with boulder. So, the fact that I hadn't heard back from boulder was because my application hadn't even been sent to the department yet! Hope it helps, Good luck to all
