“Dog-water” grades? Come on.
And I’m sure you know the schools you listed are all reaches for any unhooked applicant – even more so as an international student from an over-represented country. You are a good candidate but the issue is that there are more worthy candidates than spots available. Take your shot but be sure to have some safer admits on your application list.
Unsolicited advice-- I would strongly consider preparing for and taking wither the SAT or ACT if you are a sophomore or junior.
Good luck.
