Hi there, thanks for all the great questions!
Is it 9-5 every day? No - thankfully! In your first two years lectures, PBLs and practical sessions will be spaced throughout the day but not all days are 9-5. everyone gets Wednesday off! When you get beyond 2nd year, you're on placements all day so it's pretty much 9-5 apart from Wednesday.
There are 3 different campuses: one in West Smithfield, one in Whitechapel and the QMUL Campus in Mile End. These aren't vary far apart and most of your time in pre-clinical years is spent in Whitechapel so there isn't too much travelling about. Both the West Smithfield and Whitechapel campuses are for Medicine, Dentistry and some other medical related BSc teaching. Whitechapel contains the Perrin lecture theatre for most of your pre-clinical lectures, the Garrod Building for PBL and one of the halls of residence, Floyer House. West Smithfield is the site of Barts Hospital and is just around the corner for Charterhouse Square which contains one of the Halls of residence, Dawson Hall as well as some research institutions.
Overall, lecturers at Barts & The London are fantastic. There are a handful of regular lecturers who give most of the basic science lectures and these are very good. If you have any issues with content you don't understand, it's very easy to contact the lecturer for clarification.
So for the 'final mark', I assume you are referring to ranking which is what contributes to FPAS, the system used to rank medical students around the country when allocating foundation (junior doctor) jobs. This is actually quite a complicated system as there are multiple 'papers', each of which contains different assessments throughout the course. Only one of these papers contains the end of year exams and others contain aspects such as student selected components (SSC) and in course assessments (ICAs). More information on the FPAS can be found here:

I hope this helps!
Barts love,
Will
