I love philosophy. It's my major in my current BA degree. I understand it can come across as boring, or sometimes seem to be a pointless waste of time. I suppose it depends on how it's looked at & taught. Epistemology is the basis of science, so no less important. I've not done a unit directly on epistemology only, but I've covered it in several other philosophy units, as well as briefly in a sociology unit on research methods.
Considering the basis of all we "know" in study of epistemology is for me fascinating, and essential for rational thinking. I think it's one of those areas all human beings should have at least a basic education in if possibe.
It's also a good foundation for future learning about ideas of different philosophers, which I hope you have a chance to do also. Philosophy courses can vary greatly, so it's a good idea to research beforehand, such as looking at set textbooks.
