As a NatSci, my first and second years were pretty much the same, except I had four subjects in first year and three in second year. I'll outline the lectures etc below, but basically when I wasn't doing contact-time work, I was doing supervision work until about 9pm then went to the bar or to a friends room, cinema, formals, things like that.First year (Chem, Cells, Physiol, EMB): 12 lectures a week, Monday to Saturday, which were over by 1pm at the latest, and 9ams are likely; 4 supervisions, which can be at almost any time (weekend and evenings are quite common I'm afraid), Chem practical once a fortnight, Physiol and Cells once a week, I forget about EMB! They last most of the afternoon.Second year (Chem B, Path, CDB):9 lectures a week, 3 supervisions, Chem practical once a week, CDB once a week, Path was two short practicals a week. Chem practicals have to be written up in your own time, which can take forever.This year is very different, I'm doing Pathology as my major subject and Biology of Parasitism as my minor, for the Biological and Biomedical Sciences option. This means I have 5 exams instead of 4, and do a dissertation instead of a lab project. I have 9 lectures a week but no practicals and no set supervisions, except for my dissertation. Time not in lectures is spent (amongst faffing and other stuff) reading/writing my dissertation, reading lecture notes and papers. Time not spent working is spent in a similar was to in first and second year
