What is a difference between syllabus and topics of B.A (honours)history and B.A(hons.) LLB .
Under BA Hons History you can study topics on history of India, Languages, History of other countries as well.
Detailed syllabus you can check here: http://www.du.ac.in/uploads/old-ug-courses/27412_History_BA_HONOURS.pdf
Under BALLB:
You will study about Legal methods, History, Contracts, Pol science, Economics, Constitutional Laws etc.
BALLB is a one step ahead course for law studies. It is more professional in terms of BA Hons History.
Hope you can make the sense out of the above.
Good Luck.
