How many hours are in a one college credit?

There's no single answer to how many hours are in one college credit. The number of hours varies widely depending on the institution and the course. While a common guideline is that one credit equates to 1-1.5 hours of classroom time per week for a 15-week semester, this doesn't include time spent on homework, studying, reading, etc. The total time commitment for a single credit can easily be 3-6 hours or even more per week, depending on the course.
