By now, I am sure that you’re familiar with the unpredictability of the process so I would say, yes, be prepare and be HAPPY to attend one of the colleges that admit you.
Remember, if you don’t go to T20-T50 schools, that doesn’t mean that you are not good enough. If you apply to those schools, I assume you feel you have a chance to be admitted and therefore, you are qualified enough. We don’t know what the AOs want to see in applicant. Sometimes, it’s just the make up of the entire class that ends up deciding everything.
it is you who can decide the joy of going to certain college. Not the rankings, not your parents, not your friends, etc. So if you come with a great attitude, you’ll have great experience wherever you go.
