I don't entirely understand this - at the very end of this window (Mid-Feb), it'll be halfway through the term for most students. If they also planned on doing an early travel window for Easter return, there's a decent chance that some students might only be spending 3/4 weeks at Uni.
My department has said they think it's unlikely that we'll have in-person teaching before September; as a final year, that really sucks as that means my last lecture was in second year, in February.
