Biochem/ Neorscience/ Biomed:
Can't really answer very detailed questions, the modules run on a different timetable now, but some general stuff:
You'll all have a very similar schedule, as a lot of 1st year courses are shared across the faculty. A lot of practicals, normally 2-3 afternoons a week, in an unlucky week you can have a practical every afternoon, especially in first term, second term is more tame as chemistry labs are finished by then. The general way it goes is lectures in the morning, practicals after lunch. A lot of labs means a lot of coursework, so it's worth keeping a track of your deadlines. In BIOC1001 study for the moodle tests, the exam isn't worth that much, but on the bright side it's a multiple choice non-negatively marked pisstake.
The Neuro lot can pick only 0.5 unit Chemistry, but instead they do a compulsory 2nd year Physiology module (oh the winter test in that is a proper bitch).
Biochem people complained about 1007 coursework, so make friends with a 2nd year Pharmacology or Neuroscience student, they'll draw a Scatchard plot for you.
And Biomed is pretty cool, compulsory Anatomy in the creepy Rockefeller dissection room aside. And you can pick what you want to do at any point, or graduate with a broad degree. In first year (applies also to Neuro ppl) go to your pharm tutorials, they'll go over exam stuff a million times there.
Find out who's the teaching administrator for your degree and for anything major contact them in the first instance, they all live in the biosciences teaching office now. Staff is generally approachable, so when you don't understand after looking up in a textbook or on pubmed, email your lecturer- they won't bite your heads off, they may laugh at you a little while sipping coffee at the laptop, but they'll usually answer pretty quickly and possibly save your exam mark.
