I need a little advice here. I applied for a C programming job at a game company and there is an all-day at-home test involved. Other than studying up on everything, which may not be practical, I'd like some ideas from the experienced people out there on good things to brush up on and what I may likely expect.

I know plenty, which is why I got a reply, but it's my first programming job opportunity, so I lack actual real world experience and don't want to screw it up over something stupid.
