Hi,
I'm in second year but I had exactly the same problem last term, I only had 6 hours a week. I spoke to my tutor about it and she explained how for every one hour of lectures I have I should add on three hours of independent study. I don't know whether that would be the same for you but university is all about doing independent work, something which I took a while to learn.
I know how it feels to see people getting more hours of lecture for the same amount that you pay, for less lectures, but you could also spend more time doing extra actives like volunteering/ part time job/ society which will look good on you CV once you do graduate!
Hope this helped.
