Dude,
Round 3, Wharton, a 3.1 and an erratic work experience... you may be jumping the gun a bit, and you may want to reconsider your school list a bit too.
So first of all: what's the rush???
I mean round three is TOUGH unless you got some Ace up your sleeve (your dad a CEO maybe?
)
So maybe if you have a good reason, you rush the app, but it DOES hurt your chances.
Soooo, I would say wait.
The FIRST thing you gotta do for sure, is work on your story. I mean you have a LOT of job changes there in a very short time. And somehow you gotta build this all up into one story arc with one goal. So you gotta figure that out first.
So Conclusion: yep, you're nuts.
But we like crazy people. And believe in your ambitions. Doesn't mean one can't strategize cleverly though, yeah?
Sooo, you knew it was coming: Take stock, start thinking about R1, and in the meanwhile do what yo can to improve your profile...
