Hi lukethesamo,
It looks like you've added random letters in parentheses to the end of most of the building names across the university - what do they mean? If they are some kind of internal reference then I think the ref=* tag may be a better place for these.

Secondly a tip when drawing new buildings: if the corners are right-angles use the "Square" tool (right-click, or keyboard shortcut Q). This can be done for an individual corner or for the whole building at once.

Happy mapping,
Jez
