Continued Education Classes (Santiago de Chile)

Does anyone know if it is possible to enroll in just a class or two at a University? I would like to take some literature and education courses, as I am planning to get a Master's in Teaching when I move to England next year. There are some prerequisites that I was hoping to get out of the way before I went, and was hoping to be able to do some here without enrolling in a full carerra. Thanks in advance!
