When to tell your roommate and closest friends you are transferring?

Yes, it was at a well regarded four year LAC. Very common for those with guaranteed transfer options (GTOs) to Cornell University.

I have no idea as to whether Cornell GTO requirements allow one to satisfy them at a community college.

These were all very bright, accomplished students who targeted specific programs at Cornell University.

As an aside: They all were very attractive, articulate individuals & seemed to avoid any social events with alcohol. The guy was headed to the hotel management school & I do not know which school at Cornell the girls were transferring to, but it was clearly Cornell’s gain & our loss. Now that I think about them, I recall that all 3 were sons & daughters of college professors or administrators who attended tuition free on a tuition exchange type program.
