TC3 has a good honors program and dorms, and may be a surer way to Cornell than Cobbleskill. Look at both of them up and compare the environment, dorms, campus, class offerings, etc.
But frankly, with your stats, I don’t think either would be appropriate.
Bing is a very good university and it’s become extremely competitive since the Excelsior scholarship.
In early May, colleges that miscalculated yield are placed on a list so applicants unhappy with their decisions can try and snag a spot. There are always excellent colleges on the list. If your common app is ready, contact the reference whose name will appear on the list, introduce yourself, explain why their college is of special interest to you and be ready to send that app.
It shouldn’t be Cornell or bust!
