LIFEPAC resources promote the principle of mastery learning through the use of engaging lessons, activities, review questions, and tests, all with a focus on biblical truth. Rather than following a rigid assignment schedule, students are allowed to master the content in each unit workbook before progressing to the next. Subjects and grade level workbooks can even be mixed and matched to personalize each student’s curriculum content!
