When you're away from Oxford during the vacation, you can still access electronic resources (e-books, e-journals, bibliographic databases, reference works, etc.) from wherever you are by signing on to SOLO or OxLIP+ with your Single Sign On username and password before you start searching. More information on remote access to e-resources is available on the Bodleian Libraries website.
If you are revising for exams and need access to past papers, you can find these on OXAM (you will need to select 'Oxford Account Login' then enter your Single Sign On username and password to access the resource). OXAM provides access to formal examination papers set by the University of Oxford since the academic year 1999-2000; as well as Mods, Prelims and Finals, it also includes papers for taught postgraduate courses.
