An "introductory course" is a foundational class designed to provide students with basic knowledge and skills in a specific subject. These courses are often the first step for learners who are new to a field, such as mathematics, biology, or computer science. They typically cover essential concepts and terminology, helping students build a strong base for more advanced studies. Introductory courses are commonly offered at various educational institutions, including colleges, universities, and online platforms. They may include lectures, readings, and hands-on activities, allowing students to engage with the material. Successful completion of an introductory course often prepares students for subsequent, more specialized classes.
