Dear Aspirant,

First let's see the basic difference between BSc. LLB and B.A. LLB. Both of them are integrated courses and the general duration for these courses across the universities and colleges on India is of 5 years as they are an integration of Bachelor of Science and Bachelor of Arts respectively and with that the subject matter of law is also imparted to the candidates. The subjects for the law remain the same but in BA LLB, arts, humanities and social sciences subjects were also integrated. In BSc LLB, Physics, Chemistry etc. such subjects are integrated. One major problematic aspect of this is that only B.Sc. LLB can only be pursued by those students who have studied science in 10+2 as their main subject. Owing to this, if you are a science student and you wish to apply for this, the option is available but otherwise it is not so that naturally pitches BSc LLB out of the picture.

Subjects like History, Geography, Polity, Public Administration, Economics, Ecology, Environment, Science & Tech, Philosophy and Psychology are a part of General Studies paper which are all humanities subjects. So it will give you a upper hand in the paper and you would not have to utilise your time in understanding the subject later. So BA LLB works for people from any academic background and also aids the subjects that are to be studies in IAS.

Though this doesn't mean the BSc. LLB is not a good option as it can also aid you in your optional subject. Nevertheless, Take something which interests you more and fits your understanding of the same.

Hope this helps. All the best!
