First Year College?

I’ve read about the process of transferring into a major, but for any undergrads out there who were in FYC, can you tell me what steps there were to get into the major of your desire. Also, how long do you have to decide to transfer (1 semester, 3 semesters…)?
I’d want to transfer into engineering asap.

You will want to go into First Year Engineering, not FYC. It’s a one year program, then you matriculate into one of the engineering departments. All freshman engineering students take the same classes.
