I study Chemistry, so my course is a little different to humanities etc. and has a lot of contact hours (which I'm fairly sure go up each year), and in the first year I had compulsory maths as part of my course, plus one extra subject I could chose (I did Ancient Rome in the first semester, and History of Medicine in the second). In an average first semester week I would have four Chemistry lectures, three Maths lectures, three Ancient Rome lectures, a Chemistry tutorial, a Maths tutorial and an Ancient Rome tutorial (every other week) which were all 50 mins long, and a three-hour lab session.
In Chemistry we did a mix of organic, inorganic and physical in both lectures and labs (tutorials were based on lectures). We did I think six different topics, each one led by a different lecturer and relating to one question in the final exam, and we had a handbook explaining the different experiments we would do each week, relating to the current lecture series. Maths wasn't split up as much, it was the same lecturer going through all the topics and then the tutorials just echoed the lectures.
I've only been in the first year labs so far but they're large, new equipment, lots of fume cupboards so you're not all cramped up, lots of PhD students helping you out. Labs count for 25% of the course, the Exam for 55%, weekly assessments for 15% and PeerWise (an online question resource written by fellow students) for 5%. In Maths it was 80% exam, 10% tutorial work, and 10% Chemistry-tutorial work (specific tutorials relating the Maths to Chemistry that you get maybe twice a semester).
The tutors are great, they're always willing to help out if you email them or go to them after lectures. Your personal tutor oversees your tutorials so helps with all that work, and you do little weekly assessments which get marked by the lecturers. All in all, there's definitely enough help around if you want it.
