Ok, so I'm kinda freaking out about my two physics interviews tomorrow morning. I know most of the details on how they work though, so I should be able to calm myself in time for the interviews. If you guys could give me any advice, specifically physics or maths advice, that would be really great. Are there any topics I should make sure I'm good on? I mentioned Cosmology, so could point me to some good links you know? Also, I want to make sure I know all the important equations so I'm familiar with them when I go in. Any general help would be awesome. Thanks.
