Getting into Graduate School in Physics
It has been over 25 years since I applied to graduate school, and it has been over 5 years since I have read graduate school applications, so I was happy to see that Sean Carroll has posted a nice entry over at Cosmic Variance on how to get into graduate school in physics and/or astronomy. He starts off with the obvious.
So, here goes: have great grades, perfect GRE scores, significant research experience, and off-scale letters of recommendation. Any questions?But he then does give some very sensible advice on somethings can help you get into the best school for you. I feel that his discussion on getting to know your professors well enough that they can write good letters of recommendation for you is probably the most useful advice.
Also check out the comments. That are a lot of knowledgable people contibuting to the discussion.
