Muslim law & jurisprudence is a do-able subject. Your analysis on subject matters, though the syllabus is elaborate. I had no background of law, my sister's llb notes were only material i had. She guided me for it when next day i was giving paper. I scored 65.
So the point is you can do it. I was going to opt intl law for 2017, before the result was announced. I think we muslims can write our analysis better as our exposure with it's aspects is more as compared to other laws.
