I don't think it's a top tier economics department in London, but a decent one nonetheless. If you do well here, you should be able to pursue postgraduate studies at any top uni. For job opportunities - make sure you top up your CV with good work experiences to maximise your chances of landing a good paying job.
Problem is - normally at lesser known or non-targeted Universities - students expectations are too high based purely on the course - there are other factors that come into play.
Uni is just the start.
