Go for the sure thing!
You're not the kind of platinum-grade rock star that has an excellent chance at a Top 20 school, not with a 3.6 GPA and ECs that, while good, probably aren't jaw-droppingly extraordinary. The only way that this makes sense is if you've got truly impressive ECs (military service, world-class athletics, professional musicianship, overcame immense childhood adversity) and a 523+ MCAT. You'd probably also need a strong upward trend, too. And even then it would be a crapshoot, unless you were willing to go to a DO school in Cali.
Simply having a killer MCAT will make you pure pack fodder at these schools, not a platinum-grade rock star.
