I am really fascinated by ancient civilizations and cultures.
I do not know what subjects one has to take up to study Archaeology (like what subjects in A Levels or High School) at an academic level?
I would just like to know in general but would appreciate any details about United States and India.
You may be potentially interested in anthropology programs. Although anthropology can be a very diverse field, all I am familiar with (not many FWIW) have a devoted concentration for archaeology related studies/methodology.
