1. Can somebody tell me the things I should buy for university (I'm a first year undergraduate living at home) such as stationary, writing utensils etc. Should I apply for a student bank account, discount travel cards etc.
2. Should I invest in a voice recorder or are these a waste of time since some lecturers may not like the idea and it's not something seen that much in lectures or seminars?
I'd definately apply for one of the high street bank account student offers; as has been mentioned, you should be able to get at least £1,000 interest free overdraft aside from any other perks.
In terms of stationary, this depends on the course you are doing. I wouldn't worry about it now though. I would turn up to your first lecture with pen/pencil and paper but aside from that, you'll quickly work out what you need.
You need a wetsuit. All the other students will have one, and they'll laugh at you if you don't. You'll understand why when you get there.
I wouldn't bother with a voice recorder. a good old pen and paper does everyone i know just fine.
