How much extra work are you doing on your own? If you are only doing the minimum then I'm not surprised you are bored. And are you getting top grades for all assignment? If not, why not?
Start reading all the academic journals in your subject area (do you even know where these are kept in the library/where they available online? find out), read all the recent MPhil or PhD thesis written in your subject area (in your Uni library to borrow) - and undergrad dissertations/project work if you can get hold of them. Follow up all references and citations and/or any other bits you don't currently understand. There will also be recordings of lectures etc available for you to watch/listen to - from your own Uni and at others (google relevant keywords and 'lecture' and 'ac.uk'). Once you have done all this, you won't feel like you have nothing to do or that you aren't achieving anything.
Have you spoken to either your Personal Tutor or your Head of Dept about your concerns? If not, do so. Unless students speak up, nothing will be noticed and nothing will change.
Remember - changing Unis can sound like a great bit of defiance and is a great way to flounce out of a Uni you are peed off with. You, however, have to live with the consequences. That includes moving to a new city, starting the year on a new course that is already one year in with previous coursework you haven't done and a social group that is well established, friendships made etc? Moving to a new course/Uni may not be actually quite as instantly successful as you might imagine.
Look at the Orange Sticky thread entitled TRANSFERS at the top of this Board - lots of advice and warnings.
