It’s so unlikely that one would transfer from a CA CC to an Ivy that it shouldn’t be part of your plans.
Most transfers admitted to ivies are “lateral”, ie., coming from a similar-level university (a top 10 or top 25 universities or LAC).
To Cornell: mostly into CALS (look at the possible majors) and most from NYS CC’s.
It’s possible to transfer from a CC to a UC or a CSU, of course, but you already knew that.
Why are you starting at a CC? Why in January?
