Is this realistic?

So, I still need to complete all of my pre-reqs.. literally all of them. Due to a few hiccups early on when I was an engineering major and my father passed away and I had a health issue, my grades took a hit. I have calculated that if I received A's from here on out (Bio 1/2,Chem 1/2, Orgo1/2,physics1/2, Biochem) I would have around a 3.5 GPA. No idea how I would do on the MCAT, but knowing I'm in tight spot with not much wiggle room, I'd be willing to bet under that pressure I'd do pretty... Is this realistic?
