This study group focuses on mastering the core ideas of Calculus II through active learning. We will review key concepts, solve problems collaboratively, and work through challenging exercises step by step. Sessions will include short explanations, guided practice, and open Q&A, encouraging learners to ask questions and explain their reasoning. The goal is to build strong intuition, confidence, and problem-solving skills in topics such as integration techniques, applications of integrals, and sequences and series.
