I am an undergraduate student having some background in Algebraic Topology. I am currently interested in Algebraic Topology, particularly, Covering Spaces. I have Munkres's book, Allen Hatcher's book for self studying. These are great sources, yet they are not that easy too.
So I am asking if there are other books, lecture videos or lecture notes suitable for self-studying on these subject, any notes for preparation for reading Munkres or Hatcher.
Thank you in advance, any kind of answer is appreciated.
