I have selected following subjects

>> International Relations
>> History of USA
>> Environmental Sciences

But Confused between

1. International Law (less Syllabus) vs Criminology (nice trend)

I have viewed course outline and have interest in both subjects and can prepare them easily just help me pick one considering my combination.


2.Punjabi (finding its vocabulary difficult) vs Psychology (lengthy syllabus) vs Sociology (everyone is opting, lot of competition) vs Public administration (I know nothing) vs anthropology (I know nothing)


I'm really confused about my last subject please help me select any subject that can be prepared with reasonable effort and can be done with one book.
