From what I know there are two seminaries in Gateshead, New & Old!
I think the Old is more intense than the New regarding studies and actual students there. The New caters for more of a diverse crowd and apparently also has fantastic Shiurim. I heard there are loads of israelis there and ivrit speaking frenchies so you’ll be fine!
Gateshead really is a great place with everything a girl could possibly want or need!!!
G’luck
