Undergrad physics with low GPA
I want to study astrophysics, or physics with concentration in astronomy, etc. However, as of the end of junior year my GPA is on the low side at 3.28.
I know the top-tier places are a waste of time to consider, but assuming my SAT I is over 2000 and I have solid ECs and write a fantastic essay, where should I shoot for? Hopefully somewhere with decent research opportunities from where I can still get into a good grad school.
Basically what schools are decent for physics without being top-tier?
