That's true - you may need to retake lower courses, or show a longer positive trend - but I'd have to say it sounds like you make a very competitive student. May just be so many qualified people applied this time.
You also may want to consider being a general physician assistant as well. If AA is all you want, go for it - but if you're not sure, look around. There are multiple PA schools and most of them look more at trends (yours improving) than historical data.
