Interesting mix - for example, why did you apply to SU if you were unsure of the reputation.
Syracuse is not known for engineering but has a sizable program and is ABET - so you’ll be fine.
UCSC - how much does the curriculum match with what you’ll want?
It’s a fine school, at a fine cost - and is woodsy - 45 mins or so outside of Silicon Valley. Best I can tell only Electrical is ABET and Robotics shows up in electrical. Is it ABET? How are their outcomes - they should be able to share this with you. You seem to be mechanical elsewhere so how does robotics fit in there?
Both RPI and CSM are fine mid size schools - to me, Mines is nicer - but I like to ski and it’s on the edge of Denver in Golden, near a very neat little downtown. RPI is in upstate NY near the capital, great outcomes. Both will be more STEM focused, etc.
How does cost matter?
Does the UCSC curriculum match what you want and how are the outcomes? Is it accredited?
These are the kinds of things I’d ask.
