Is Johns Hopkins University (undergrad) hard to get into?

you should look it up b/c gpa means a lot but not everything, and also i dont doubt the 3.7 is the average gpa. of course if you have good SAT score but wants also really important is extra curricular activities. They always look for people with leadership qualities, so that would help a lot. Also try to get good recommendations from your teachers. But either way, apply if you want to, the only thing you got to lose if you application fee.
