Do let us know your results.
I’m not sure you have a shot because these are “reach for everyone”, especially since you seemed to have “shotgunned” the T20, which means you don’t understand “fit” very well. You would likely have been more successful if you’d included some State Flagships and their Honors Colleges. But, what is done is done. Fingers crossed! And who knows, you may have a decent shot at NYU since they’ll primarily rely on your bac results and are need aware.
To explain more in detail how the admission process works: there are several “cuts”.
First cut pushes aside students who don’t have the grades to keep up with the depth and pace at the university.
After that, only excellent students remain.
At that point, adcoms look at the whole profile, not their grades (since these are already dealt with): their achievements (in Ecs), essays, recommendations, and institutional needs all come into play.
Some are clear admits: national science winners, concert musicians lauded for their Carnegia Hall performance, young people whose movement made a huge difference (think Malala Youfafzai, David Hogg). Keep in mind all of these are there because they made the first cut.
Then, the vast majority of applications.
You may be a first violist and they need an oboe player so the oboe player will be chosen, not you.
Or you may be a great debater but there are 145 among applicants this year so you’re just one of 145 and they only want 6.
Therefore, your odds are really unpredictable.
Perhaps you’ll get into a French Ecole that’ll let you study in the US as part of your degree?
In terms of MBA, your grades as an undergrad will matter less than how you proved yourself worthy in your first job (as a consultant, manager, engineer, or any career-track, entry-level job.) You’ll need concrete evidence of the positive impact you made in your company or department. In addition, they’ll look closely at your volunteering hours (commitment, achievements).
The expectation is about 2-3 years on the job and up to 5 for the most selective MBA’s (often longer for very selective but not most selective category). The average age for MBA’s is 28.
