I completely agree!Whether it is high level physics research or working construction, your professional contacts are worth gold.
This is a very wise warning! Professors will always need cheap research monkeys to do their work... remember as a grad student you get paid a very petty wage compared to an adjunct who would do your job if you were not there. My brother would make more working his summer job at the mill than I would all year long- teaching kids just like him everyday...Just for the record, getting into grad school and getting a job are VERY different endeavors, with very different supply/demand issues. I don't really get not getting into grad school; there's tremendous demand for grad students. On the other hand, there is not sufficient demand to put all those students to work once they graduate.
Probably; there's someone desperate enough to take almost any student.So, if your physics gpa is 3.0+ you have a reasonable chance of getting into a decent grad school?
Exactly. Admitting grad students is almost more about hiring teaching and research assistants than admitting students. The criteria vary as a result, and if you come strongly recommended with experience in these areas it will do a lot to help make up for deficiencies elsewhere.Teaching and lab experience have tremendous value to them.
