I am about to take part in an undergraduate recruiting event at my school, and prospective undergraduates were invited to ask questions to current students of the school. One such prospective undergraduate claimed that he crossed one school off his list because that school only did condensed matter as far as physics research is concerned, claiming that the research done at a school influences upper-division electives or otherwise affects what one can get out of an undergraduate physics degree (e.g. research opportunities) I wonder to what extent the second claim is true, knowing that the first is true to an extent. When all is said and done, to what extent do subfields matter when choosing an undergrad? I know not everyone that come to an undergrad with the idea of doing physics will actually major in it, but I don't want to mislead anyone.
