Hi Laura,
In the first semester, like many other universities, the veterinary biosciences course is very broad. It encompasses basic cell biology, microbiology, chemistry, maths, statistics and a module in veterinary anatomy and animal handling.
So far I've had around ten 3hr practicals. Other than microscopy and cytogenetics, we have had the opportunity to attend five anatomy practicals where you can dissect and analyse different parts of domestic animals. For example, we had a respiratory practical where we handled a racehorse's lungs. The veterinary staff are great and many of them are within the (histo)pathology field which makes practicals really fun and interesting.
As for the difficulty of the course, I wouldn't say its a massive jump from A levels. Having A level biology helps, however other subjects such as chemistry and maths aren't a necessity as one of our modules in the first year covers the basics.
I'm personally not planning on studying veterinary medicine afterwards as my interests have always been in veterinary infectious diseases, epidemiology and public health but i know that the majority of people in my year are planning on studying vetmed at graduate level.
As for the university's night life, Rubix (the student union's club) is amazing! There are also many great bars and clubs in town.
I hope I've covered everything that you wanted to know. If you have any other questions please ask! I know how difficult it is to decide on a firm and insurance choice so make sure you find out as much as possible beforehand!
