Challenge IV is the capstone of all the Challenge levels. This Challenge encapsulates rhetorical specialization by thorough student-led seminar discussions that evaluate the most in-depth reading material of all the Challenges. The combination of ancient literature, theology, and world history encourages investigation of history in remarkable intensity. The assignments require analysis from a Christian perspective and help students develop a philosophically integrated worldview. Research in physics, more development in language usage, and logic studies in calculus complete the academic study. Upon completion of Challenge IV, the competent student will have mastered grammar, dialogued and researched in a social setting, and rhetorically discussed and presented material in several academic disciplines.
