I'm a 3rd year up at Aberdeen originally from Bath, England.
My flatmates are doing English and they seem to be enjoying myself; I did a Controversial Classics English course last semester and it was really interesting, but lots of reading (I recommend getting your books early and second hand).
I have to say that its not a cheap place to live :P It's easy to get accommodation in your first year because they uni provides it for you, but if you want a nice place in the following years, you'll have to pay the price unfortunately.
Weather is usually good - very cold and changeable but it doesn't rain that often (plus you get snow in the winter!).
The airport is about a 20 minute drive and there is a bus that runs from the centre of the city. If you get a taxi with friends its cheaper and easier to split the cost than take the bus.
There is a bus that runs from Hillhead and the main campus to the centre of the city every 20 minutes and from there it's about a 5 minute walk to the train station.
Nightlife is all in the city centre, there are some great bars along Belmont Street including Siberia (most delicious shots in the world) and there are lots of clubs off Union Street. There's a taxi rank on Union Street and a night bus that goes to Hillhead, so you'll never be stuck.
Sorry for the information splurge, but I know how it feels coming up from so far away and you want all the information you can get your hands on :P
Just ask if there's anything else you need to know
