COMMON TRAPS

Avoid these mistakes

Using the row only

A plausible option may fit the row but fail the column.

Using the column only

Recheck the horizontal relationship before choosing.

TRY IT YOURSELF

Apply the rule

Choose a short guided set. Each question appears separately so the visual rule stays clear.
