How to parse the question "How many hours did you take at the institution?" I am filling in a form for graduate research at a US university. They have this question in the previous college attended part of the application form: How many hours did you take at the institution?

What does this question mean? How many hours I have spent in college, or how many hours I have been in college classes to earn a bachelor's degree?
In the US, university education is quantified as "credits" typically expressed as "credit hours" referring to 1 hour per week of instruction for a semester (so about 15-16 hours of face time). A course meeting 3X weekly would be worth 3 credit hours and is usually expected to involve an additional 6 hours weekly of work outside class. A 4 year bachelor's degree is about 120 credit hours.

I'd interpret this the same as asking for how many credits you took with that institution, expressed in an appropriate conversion to credit hours.
