I gave 7-10 days to TP..i think this subject is a trap...its short syllabus attracts the aspirants but there is no quality book in the market specific for css...You have to consult atleast 4 foriegn books to preparw that subject which is too much for an optional subject..So US aur Islamic history is way way better than TP...
