So you have 4 APs through Junior and maybe 5 more next year. You’re not behind. But don’t collect APs for sake of collecting APs.
I don’t know your GPA or test scores. But what are you looking to accomplish by going to a ‘top’ business school. I always laugh at the term top because short of a few specific roles, outcomes will likely be similar across many b schools.
Your schedule alone won’t get you in. But grades may, test scores and ECs may.
Edit. Just looked at your chance me. Not much to add here. If you have Babson I’d look at Bentley. And as a UNC sub I’d add IU. UNC is unlikely but IU is highly rated and likely. Not saying to swap but consider these two as additions.
Don’t forget you can score big money at other schools and your parents can get back their college savings accounts…if that were a preference. Last chain you thought that wasn’t possible. Good luck.
