Just today, I received an email from my region's West Point admissions officer, and she said that I got into the US Military Academy Prep School. After doing some research, I was still a bit confused as to what is USMAPS? Is it a high school, a junior college? Furthermore my admissions officer said I could accept the offer on my candidate portal in the overview section, but I don't see any option to do so. Furthermore, her emails always have a download that says log in key chain? What is that? Lastly, is it weird to be accepted to USMaps but not SLE? Sorry for the questions, and thank you.
