It definitely depends on the major and university. For Connecticut I would strongly advise potential CS majors to avoid going to a community college. If they transfer to UConn they’ll have to start the CS curriculum from the beginning since UConn doesn’t convert community college classes to UConn classes for CS. I think the CT State universities are a little more generous. Even many natural science courses don’t transfer. So in this case you’ll need to retake them or just transfer early.
This begins to defeat the purpose of going to a community college to save money. Many people do have difficulty maintaining a full-time course load in engineering fields, but it’s usually not because they have to retake classes they’ve already passed.
It seems like these problems are less common in other states. The fact that UConn is the special snowflake of Connecticut public universities and has far more academic offerings than the others is probably the cause of this.
