I do a different course but I feel kinda the same way - midway through 2nd year my thoughts are more 'must get a 2.1' rather than this course is amazing and enjoyable.
Talking to people over Christmas the consensus seems to be that unless you really want to do further education or love your course its just more learning to get a job and not amazingly stimulating. Unless you don't care about your results or what you enjoy doing gets you great marks, its all a bit difficult.
