Is there any pattern in difficulty level among games within an exam section?
The logic games appearing in a particular exam section vary considerably in difficulty level. More challenging games tend to appear later than easier ones, although you may find the second or third game to be more troublesome than the last game. It is safe to say, however, that the first game will not be your most difficult one.
Logic games can vary considerably in difficulty. Challenging games typically appear later in a section than easier ones, but this is merely a general rule. Expect the first game to be comparatively simple. However, you may very well find the second or third game more difficult than the fourth one.
