Nível/curso synonym trouble in lesson 6

In Level 6 (“Hopes & Dreams”?) new words, we’re given one word, “nível,” which means level or degree, another, “curso,” which means course (of study), and then “fazer um curso,” as meaning to get a degree. I’m sure this may be one way of saying it (even if the more common term is licenciar-se), but couldn’t it also mean, and more commonly, to complete one course?

Just saying this is an unnecessarily confusing grouping of vocabulary terms.
