Not a toss up, especially if you applied CS. This is in the reach category. And, if you do get in, can you afford it? It will be upwards of $80K/yr.
Your only assured college is not actually assured, is it? As you say you would only consider it if you get a certain scholarship.
So what is your likely? UIUC? Did you apply CS or Chem?
I’m concerned your list is a bit reach-y. Do you have one sure thing that you’d be happy to attend? Or are you asking for suggestions for that?
