Community college is ridiculous for her (she can keep it as a backup financially and safety wise if the sky falls, but she shouldn’t have to use that) unless your budget is under $10K out of pocket living at home or you don’t want her living away … Montgomery College program is OK, but MD is not California, so the CC->UC path … not really.
… UMBC has very large scholarships and she is even a candidate for Bannaker Key at UM-CP. UMBC is a fine school … UDel has a fine honors program and merit aid. Salisbury would be better than community college.
UMD-CP is $25K a year total, including room and board. She could commute to there or another in-state option … The education is excellent, the honors programs are excellent, engineering is excellent.
Chemical engineering is not a good pre-vet major, only advantage is overlap between pre-med and early engineering classes, but it is really hard and would also likely not meet her interests if this ended up being her career. I would think biomedical, biotechnology, agricultural engineering … or say biochemistry … would be a better fit. If you are say mechanical engineers and she likes physics 1 mechanics, you could consider ME, EE if more electrical … possibly she could design some medical / vet equipment.
Case Western, Tulane, URochester all give good merit aid, which puts you in the $35K a year type price range.
What is her budget, exactly ?
