F.B.I. Academy, after or before college?

Okay guys! So I am 14 years of age and have been thinking about joining the F.B.I.'s B.A.U. of course I know that at first I will start out as a field agent. But this is besides the point I know that I will need sociology, criminology, physiology, criminal justice, degrees at least, if there are any other degrees that I need please let me know. What I was wondering is I know I will eventually have to go into the F.B.I. Academy sooner or later, will this be postmortem to college or before? I also know that I can intern at the F.B.I. after I acquire the proper qualifications, will this also be after the F.B.I. Academy, or right after college? I know the age I have to be as well. Please help me out the best you can! Thank you! Also, don't forget to site your source so I can read up on it!
