Often the hardest part of Calculus II, this book provides a step-by-step roadmap for convergence tests. Finding the PDF: What to Know

If a chapter is confusing, watch the corresponding lecture video. Seeing the math drawn out in real-time makes the text much easier to digest. Final Verdict

Banner walks through problems slowly. Don't just look at the solution—try to solve the example on your own before reading his explanation.

Most calculus textbooks are written for professors, not students. They are dense, heavy on formal proofs, and light on the "why" behind the math. Adrian Banner wrote this book based on his popular review sessions at Princeton University, specifically designed to bridge the gap between classroom lectures and actual understanding.
