Just got this today, and I'm well chuffed with the result. I didn't make any attempt to change my good-coding-habits to the M255 bad-coding-habits on a matter of principle (a bit stupid in retrospect) so I was expecting the worst, and was frankly a bit surprised with the 97% mark I received. I thought that my TMA03 paper was better, but it will be hard to top that, we'll just have to wait and see.
My cunning plan of maximising my skills to achieve a result with the minimal effort seems to be working so far.
