Although once you get accepted, some colleges (at least mine does), allow you to pick the title of choice regardless of legal gender. You just need to stop by at the records office and ask them to change your title to Mr. Now all of my class schedules, grade reports, and anything else from the college is addressed to "Mr. XXXXXX X. XXXXXXXXXXX." They do have to keep your legal name though, but if I remember correctly, you have that changed already.
