University degrees come in various levels, including associate's, bachelor's and master's. You earn a degree by completing the required curriculum in a university study program. Degrees hold more value than diplomas; however, pursuing a degree can be more expensive and time-consuming than pursuing a diploma.
The word "diploma" refers to a certification document, while "degree" is linked to an earned title.
