When should I transfer?

So per the Gtown website, you need at least 12 credit hours but not more than 2 years.

They note typically a B+ is needed to be considered.

You’ll need a college profs recommendation - so can you get that having just started? Are you getting to know any? And an SAT score.

The last stats published (2019) show a 9% acceptance rate for transfers.

I think the best answer to your question is to contact admissions (202) 687-3600 and ask to speak to a transfer counselor.

Transferring is tricky - and it would be best (IMHO) to talk directly to the source rather than hope folks here know the nuances of the particular institution.

Good luck.
