Teaching methodology
My teaching methodology for AP classes is focused on making challenging material accessible, engaging, and understandable. With over 8 years of tutoring experience, I tailor each lesson to the student’s unique learning style, whether that involves breaking down complex concepts, reinforcing key topics, or practicing exam techniques. I prioritize active learning by encouraging students to solve problems independently, ask questions, and apply their knowledge to real-world examples. I also emphasize time management and test-taking strategies to help students perform under pressure. Above all, I aim to foster a deep understanding of the material, so students are not only prepared for the AP exams but also gain skills they can use in their future studies.
