If, by “fair shot” you mean “only 10%-15% of the applicants like the OP are accepted”.
Don’t start giving kids unrealistic expectation. Unless somebody is a kid of somebody famous and powerful or a super donor, or is a recruited athlete, there is no such thing as a “shoo-in” for any of those colleges. Johns Hopkins and Northwestern are reaches for everybody else, while Northeastern and Georgetown are never more than high matches.
We’ve seen enough kids with similar stats as the OP be rejected from colleges which are considered “less selective” that those on your list.
While you are competitive for all, the list is made up almost entirely of high reaches. If this is your list, then there will be a high likelihood that you will end up attending OSU.
That being said, OSU is better at ChemE than about half of the reaches on your list.
In all honesty, with OSU as more or less a safety, why would you apply to UPenn, Columbia, WashU, UCLA, or Vanderbilt? Even Johns Hopkins, Princeton, Northwestern, Princeton, Harvard, and Duke are not that much better than OSU, and they will cost almost 3X as much as OSU.
As for UChicago - why are you even looking at a school which has no engineering at all?
The only colleges that you should even consider there would be MIT, Caltech, Michigan, G’Tech, Berkeley, and Cornell. To that, you can add Delaware, Wisconsin, UIUC, and Purdue.
Only add other colleges is your NPC results indicate that, if you are accepted, you will be paying less than you would pay in-state as OSU, or close to that, IF that is affordable.
