The **grade calculator** is a student's best friend. It allows you to track your performance throughout a semester by inputting grades for various assignments, quizzes, and exams, each with its own weight. The most powerful feature is often the **final grade calculator** module, which tells you exactly what score you need on your final exam to achieve a desired overall grade in the course (e.g., an A, B+, etc.).
