How do you know that these other universities are going to be any better? Is there any risk at all that you are just being a bit flighty? Do you have unrealistic expectations or is the teaching etc really as bad as all that? I don't ask this to accuse or belittle you, but these are things you really need to think about, and they are what I have my students think about for a couple of weeks before they withdraw or think about transfers.
It's not always as easy as just transferring institution, either - you have to do a lot of running about to make sure that it's possible, and sometimes the target institution itself won't know if it is possible until the new academic year intake. There's a BIG thread somewhere on here about transfers, that will be worth a look.
There is a lot of stuff to weigh up here and ultimately none of us can do it for you.
