Take the AWA on practice tests in the future. I know you don't care about the score, but you do have to write the essays on the test, and they come first. This makes the test an hour longer than you have been practicing, and that can affect your multiple choice score negatively.
FYI: Your current scores may be somewhat inflated because you skipped the essays - it doesn't happen to everyone, but it's more common than not to discover that skipping the essays helps your multiple choice score. I know that's not great news to hear, but better to find out now than on test day!

Or do you mean that you find it difficult to concentrate (on anything GMAT-related) for long periods of time? I have different advice, depending on the situation, so let me know.
