A lot of uninformed posters on here are giving you the wrong impression, unfortunately.
JHU would be an extreme extreme reach (it’s also much harder to get into than UCLA where the acceptance rate is artificially low by everyone in California applying):
http://hub.jhu.edu/2015/03/27/johns-hopkins-class-of-2019
Overall acceptance rate = 12%
Average GPA = 3.92
Mid 50% SAT = 1430 to 1560
Mid 50% ACT = 32 to 35 for admits
Percent in top 10% = 93%
UCLA is a few notches below in selectivity in test scores. A lot of high schoolers on here with out a clue. I see you potentially getting into several of the other schools on your list, however.
