durham study places (and uni facilities)

If you’re just looking for somewhere warm and free and relatively quiet to study then why not try the cathedral: https://www.durhamcathedral.co.uk/articles/warm-spaces-initiative

hi, i'm a sixth form student living in durham and i have some v important exams upcoming, but since lots of facilities are closed over the holidays and i can't work well at home, i'm struggling to find (free) places outside where i can actually focus.
since i'm not 18, i can't get a bill bryson visitor card and my school is small so unable to arrange a session thing like they have on their website.
does anyone know any good places to revise? and can i use the buildings which don't need a student id to get into? for example the teaching and learning centre has lots of study spaces and i would assume it's not too crowded because it's xmas hols, but please correct me if i'm wrong - would i be able to just go in and study there for a little without being a nuisance?
wi-fi isn't a requirement as i could download stuff at home then use those resources wherever
any ideas would be useful, i'm really struggling to study atm
