A demo course is a short, sample version of a full-length course that is designed to give students a taste of what the complete course will be like. It is often used as a marketing tool by educational institutions or online learning platforms to attract potential students and showcase the quality of their offerings.

The "Fundamentals of Psychology" refers to the basic principles, concepts, and theories that form the foundation of the field of psychology. This encompasses a wide array of topics aimed at understanding human behavior, thought processes, emotions, and mental health.

A demo course typically includes a few selected modules or lessons from the full course, as well as some introductory materials and information about the course structure, instructor, and learning objectives. It may also include interactive elements, such as quizzes, assignments, or discussion forums, to give students a sense of the course's interactivity and engagement.
