How does "transferring" to Perimeter work?

I’m an incoming freshman and I actually ended up applying to the wrong college for GSU. I want to study civil engineering and I should have applied to GPC since they have the RETP program (you do well for two years then transfer to Tech), but I didn’t exactly do my research ahead of time.

I paid the housing deposit and registered for classes at GSU, thinking I might as well transfer, but what’s the point when the engineering program already exists at GPC?

My main concern is that I don’t really know how to go about switching from the Atlanta campus to GPC so that I can take the right classes. I don’t think that should be too much of an issue, since I’ve already been accepted to GSU, right?

Any suggestions would be greatly appreciated. I will be giving GSU a call ASAP.

Cheers
