We are District 13. The real answer to your question is "it depends." Upon how many apps there are this cycle and who they are! Some academies are doing some aggressive recruiting of kids from certain areas, kids with a particular athletic skill, ethnicity, etc.
You can only control your application package. Make that package as strong as possible regardless of whether your district is perceived as "tough" or "easy" to get a nomination in......then you will have done all you can do.
