For example:
* High school: A single high school course might be worth 1 credit.
* Undergraduate: A college course could be worth 1, 2, 3, 4, or even more credits, depending on the number of contact hours per week and the amount of work expected.
* Graduate school: Graduate courses often carry more credit hours than undergraduate courses.
To find out how many credits a specific subject is worth, you need to consult the course catalog or syllabus from the institution offering the course.
