See if anyone at your college has contacts with admissions at JHU and ELSEWHERE and take their advice as to how to proceed. Unless no help is available to you, stop trying to proceed on your own. Part of your tuition goes to administration and guidance, let them work for you. At the right place it means a lot when someone who has been in this business for 20 years calls an admissions person at a college that they know and who knows them and says, this person is an extraordinary student in my experience and you will be happy you accepted this person because etc.
