It will depend heavily on med school and obviously what year you are in.
Oxford: Traditional course, minimal early clinical contact, basic science focus. Compulsory intercalation (i.e. 6 years).
Pre-clinical
1st year: Lectures at 9am every day. Between 2 and 4 hours worth, all basic science. Practical (physiology labs, biochemistry labs or prosection) in the afternoon 2-3x per week, tutorial in the afternoon 2-4x per week college dependent. Expected to do an essay for most tutorials, which probably forms most of your work.
You visit a GP/hospital ward for an afternoon once per term.
Exams (essays and MCQ) at end of the year. Mock exams at the beginning of terms.
Just 3x8 week terms
2nd Year: Similar to the above for first two terms. Focus shifts to using more primary and experimental evidence in your essays rather than textbooks. Exam (essays and MCQ) at beginning of 3rd term, then change to intercalated BA which is very different:
People often say this year is the most difficult as it crams what should be 3 terms of work into 2 to make room for intercalation.
3rd Year: Far fewer contact hours. 3 main aspects: Taught aspect, research project and extended essay.
Taught aspect - you might have around 5 lectures and a seminar per week but as you select modules you aren't expected to attend them all and attendance drops way below 1st and 2nd year. Just 8-10 tutorials for the whole year that you have to book yourself. Exam (essays) at end of year.
Research aspect - have to organise your own 8-10 week project. Usually you help with part of someone's PhD project, doing research no one else in the world has ever done before which is cool. Usually 9-5 or thereabouts. Write up as if its a publication (and indeed many do get published).
Extended essay - write an extended essay on a topic of your choice. Supervisor available to guide you.
Clinical
Note: about a third of the year will have gone to London at this point. Some choose to go, others lose out in a re-application process including interviews. Assuming you've passed, you are guaranteed to get in somewhere no matter how bad you are!
Terms from now on are around 48 weeks per year.
4th year: Med ed - 3 weeks of learning how to take a history, examine patients on the wards 9-4ish.
Lab med - then straight back to the lecture theatre, 9-5 most days. For the first time you are learning actual medicine though, as opposed to human and microbial biology. Exam (MCQ) just before christmas.
Then clinical attachments proper. Various rotations, expected attendance varies. Can be long days but lots of scope for leaving early if you're bored. Small amount of logbook work. Clinical lectures on Fridays.
Everyone really loves 4th year.
Formative (mock) MCQ and OSCE at end of year.
5th year: Most intense clinical year. 6x8 week rotations with exam at the end of each (MCQ and OSCE). Actual day to day is a mix of lectures and (mostly) clinical attachments. Might have to do a handful of night and weekend shifts. Again, attendance is largely governed by what you find useful, with a small amount of logbook work.
6th year: Repeat of 4th year clinical rotations but with your motivation now being finals at the end of January. Even more self-motivated as even the strictest of consultants tend to forgive you for wanting to revise at home/in the library.
After that its elective for 10-11 weeks, then self-selected modules as an opportunity to gain experience in what you want. Good opportunity for publications again.
Basically its 6 months to relax before work.
Finish beginning of July.
Start job in August.
