As a prehonours student, work load is very managable and as a science student I have around 7 hours of lectures and 6 hours of practicals/tutorials per week. Typically, assessed course work is essays or lab-based practicals, with each course having end of semester exams as well. The balance between coursework and exams varies depending on the course but typically has been around 60% for exam and 40% coursework for me. Quality and speed of feedback highly varies depending on which school you are part of. Some work has very poor feedback or no explanation of the allocation of marks. On the whole I have found the feedback on more significant pieces of work (e.g. essays) to be much more helpful. It can take several months for essay marks to be given back, however the geology department manages to get work back to you within 2 weeks of it being handed in, which I find very useful as the work is still fresh in your mind. Course specific facilities are also excellent, with the geology department running running regular fieldtrips as part of their courses and focusing very much on practical experience in the labs as the degree programme goes on.
