WashU, CMU, RPI for Physics?

I’m intending in majoring in physics, likely with the intention of pursuing grad school. I’m especially interested in particle physics. The ability to participate in undergraduate research is important to me.

You were accepted to all of these? Costs?

Yes. I’m not totally sure about costs but I was hoping for a judgement of the physics programs and general enviroment at these schools without factoring the cost.
