We recently had a panel discussion with several program directors, and they mentioned that AOA is kind of redundant, so it's not something you should kill yourself trying to obtain or freak out if you don't get it. They know from your transcript and MSPE that you are an excellent student and at the top of your class, they can tell from ERAS your activities and leadership, they don't need those 3 letters to tell them that. They also mentioned that senior AOA is much more valuable than junior AOA, because they care more that you were a rockstar in 3rd year, not the first 2 years.
Basically OP, if you're just coasting along now and getting a 93%, great. You're bright. If you think you can put in more effort without over exerting yourself, go for it. I certainly wish I could "coast" at a 93%. But you are just starting out, and there is a very real possibility that it won't always be that easy. I just don't want you to have this idea in your head that your life is dictated by numbers and 3 little letters.
