There are two basic approaches to sketching grouping games. One is to make vertical columns for each group, another is to make boxes. TestSherpa makes boxes so that it’s easy to differentiate a grouping sketch from a matching sketch if you have extra time and return to a game during the test. If you prefer columns that’s fine, just make sure you do your sketches the same way every time you practice so that it’s second nature come test day.

You’ll lose that time and more trying to make sense of the mess later.
