These are not usually offered as separate courses, but as topics of discussion in philosophy courses. This is done so that the student has a more balanced understanding of philosophy in general.
You might also find that epistemology is taught as part of a course on religion or mythology, while cosmology might be part of a science-based astronomy course.
You might also try looking for philosophical discussion groups at the student center, the library, the coffee houses and the local bars.
Otherwise, try to board the train from Platform 9¾ at King's Cross station in London. The train leaves at 11:00 am.
