I've tried something like that. I would rate it 10. And no, it didn't work out because life itself became so uncompromisingly rigid. My advice is if you're a uni student who hasn't the means to get any good paying jobs (i.e stuck with award paying shit jobs), but still have the means to stay home and just bum off your parents, then do it. Otherwise you'll find yourself spending most of your money earned on rent, resulting in a near-zero net of asset growth.. or working so much that you have no life to do anything else. Either sucks, so if you can just keep bumming off your parents till you finish uni and get a proper job, then do it. An even bigger no-no if you're aiming for good marks at uni, which you said you are.
