You really don't need a stethoscope for first year. I don't think we use them until third year and I think it's the same for most places. Having said that, I bought one before I came, it's just a nice way of treating yourself I think and I use it to practice taking BP. If you want to get one you might as well. They won't be any cheaper or any better in a few years time, so as long as you can look after it until then go for it. I also bought a skeleton, wish I hadn't, it's just in the way in my room, never use it. Can't really think of what else you might need aside from textbook recommendations but I don't know what ones are best for the course at BSMS.
