Make sure that the school that you pick has a reputable program. Also, when you visit, try and talk with some students which aren't recruiters and see if they like going there.
Also, if you get the chance, got to www.ratemyprofessor.com
and then you can look up some of the professors from that particular school and see if any of them are good or not.
Other than that, any science related field is going to be a blast. Just don't give up. :surprise:
