After diligently reading over the Powerscore Games book twice, and solving all 100 problems in a practice book, I've managed to bring my acumen for practice Games up to speed and near-perfection, but I still find myself only solving 21 or 22 problems correctly. There's always a slip. For instance, I worked through the October 1997 Game yesterday and missed two questions that, in retrospect, I could have solved easily.
Has anyone had a similar experience with a "glass ceiling" for the Games section? How did you overcome it?
