As the AP course syllabus requires the completion of unit personal progress checks, today Matthew worked on the PPC for Unit 3. This served as good basis for review and provided the opportunity to discuss the Second Amendment as interpreted by the US Supreme Court, to analyze how to answer an AP concept application question ,to analyze and answer a graph interpretation question. Further, we reviewed Matthew's AP homework essay response , and I provided suggestions on how to elaborate responses in order to score full credit on the exam.
