The workbook label 'Diplomate, American Board of Optometry (ABO)' names the status awarded after this examination, rather than a separate examination; the assigned slug is preserved.

This original 20-question sample covers selected topics across the outline. It does not reproduce official exam questions or cover every tested topic.
