Kind of, if you read a little bit between the lines. Consider if you need brain or aim, and focus on the thing you're lacking. Try to watch proffessionals steaming, it'll probably help as well. And a personal advice: go play DM and focus on ONLY making onetaps with AK. It'll force you focus on aiming on the head, and eventually you'll get better so that you even in chaotic situations will keep your cool and aim for the head because you're so used to it.
