The TAC Certification Series, a set of 14 books with colorful covers. - Textbooks - Subject-Specific Problem Sets - Year-Specific Problem Sets There are no markings in the textbooks. The subject-specific problem sets have some circled markings (see photo 4). The year-specific problem sets have almost all ○ and × markings (see photo 5).
