Your post is important. You can still do everything right, and NOT be admitted to your first choice. It happens a lot. The colleges are looking who to give their golden ticket to. They have lots of buckets of “types” of students. The one who got picked ahead of you may have been in the same bucket, and they didn’t need another so soon.
Don’t beat yourself up. All you can do is work hard, and be yourself, and pray for a little luck. The good news is success is not dependent on the name of your college.
