There is several ways you can improve on your own time. I'd suggest first going to the multiplayer maps and going over them, figuring out where everything is, the powerups, the rocket launcher, whatever weapons you choose to use. If you can hook up another controller or two and as you look around the map remembering places try to score three headshots on your nonmoving enemies, don't kill unless you get it in three.
A nice way to improve your aim is to set your sensitivity to 10 and play through Campaign on either Heroic or Legendary. This will help your pistol and sniping aim a lot, you can move it back down to 4 or 5 once you've practiced enough and it should tone down your shot.
Lastly, if you're smart enough you can remember the spawn times on the maps, and be beside the overshield or cammo each time one of these items spawn, it should make it a lot harder on your brother having to fight you if you have one of these advantages. If you wanna know anything else mail me at shadedhalo@yahoo.com and I'll be glad to help you out.
