Lecture notes are written records that students create during a class or lecture. They help capture key points, concepts, and ideas presented by the instructor, making it easier for students to review and study later. These notes can include summaries, diagrams, and examples that clarify the material being taught. Students often use different methods to take lecture notes, such as the Cornell method, mind mapping, or simple bullet points. Effective lecture notes can enhance understanding and retention of the subject matter, aiding in preparation for exams and assignments.
