What are the necessary prerequisites for understanding Gravitation?

[billbrown1997]

I recently got my hands on a copy of Gravitation by John Wheeler, Kip Thorn and Charles Misner. Reading the first few pages are very discouraging. The limit of my physics knowledge are from taking high school physics. What book would give me the knowledge I need to read Gravitation?

General relativity is typically taken as an advanced undergraduate or as a graduate course. Having the prerequisites involves studying mathematics and physics for several years. It will not be sufficient to simply read a book.

Combat Special Relativity before you face that monster of a subject.
