The English tertiary workbook not only includes students at universities and colleges but all students looking to further their education be it through a formal institution or even online studying portals. For your courses with heavy workloads, one book could be used per subject. For ‘lighter’ courses like your online certificate courses, one section in the workbook could be sufficient. The choice is yours because of the volume of work. A book consists of 12 chapter sections, with 14 summary pages per chapter section.
