Yes, that's one of the limitations of a wrong answer journal. You can identify the mistakes, but it is a little harder to stop making them. One thing I would recommend is going back and redoing a fresh copy of previously missed questions after a few weeks or a month (whenever your memory of them starts to fade a little). Make sure not to just pick the correct answer because you know it is right, but actually refigure out why the right answer is right and why each wrong answer is wrong. Since you will have to figure it back out a little, that can help wire in the correct reasoning and can help avoid making that same mistake again.
