101 courses span an expansive range of disciplines. You'll find them in STEM fields (like MATH 101 - Calculus), humanities (e.g., ENGL 101 - Composition), social sciences (e.g., POLS 101 - Introduction to Political Science), and many more.

Despite their diversity, most 101 courses share a common goal: exposing students to a discipline in a way that feeds into future learning. They're not just about content acquisition; they're about developing critical thinking skills, research methods, analytical techniques, and subject-specific vocabulary that will prove indispensable elsewhere.

For example, a chemistry 101 course could spark an interest in pharmaceuticals, environmental sustainability, or even cooking. Who knows? The next great gourmet chef could be discovered in an introductory chemistry lab!
