This is something like the FOURTH time you've created this topic. There's no need to quadruple post across multiple forums. Also, worrying isn't going to do you any good. Finish as strongly as you can. What good is someone saying "yes, I had my acceptance revoked from BU" going to do? Is it just going to validate that you should try as hard as you can in your last semester of college? Haha, hit the books and stop worrying. Keeping your acceptance is on your shoulders, and your shoulders only.
