OK; so lets regroup for a second. Officially; you won't become an applicant until this June/July when you start filling out the forms and your application. Until then, there won't be any interview from your ALO. And you not hearing from them is not something you should really worry about. There are two things you must realize. ALO's don't normally have just 1 or 2 applicants. They have many. And between the months of around July to February, these ALO's are very busy with the applicants trying to get into the academy this cycle. Also; ALO's for the most part are all volunteers. They have other "Paying" jobs. Being an ALO may be a 10, 20, or more hour per week activity, but it's not their full time paying job. So you have to realize that they have a lot on their plate. Your ALO may have changed, but don't worry about it now. It really doesn't matter until you're a actual applicant.
I'm glad that you're still a junior in high school. I was under the impression that you were an applicant, and thus were way behind the eight ball here. You have plenty of time. Once you become an "Official" applicant, your ALO will definitely be in contact with you. Best of luck, mike....
