Hi there,
While you are preparing for CLAT, it's variable when marks are concerned, but you must aim for 160+ to get into top 50 i.e. for NLS, Bangalore.
However, it depends on the current year. However, going by past trends 160-170 marks shall make you stand amongst the top 50s.

Hi,
If you are talking about age limit then it's a no for pursuing LLB.
There is no upper bar as such.

The Institute of Law, Nirma University offers 5-years integrated Programme BA LLB (Hons.) and B.Com LLB (Hons) while the Maharaja Sayajirao University of Baroda offers LLB and BALLB (Hons.). Nirma is a private university while MSU is a government one. The fees have a huge difference and thus the facilities also vary. The extra-curricular activities provided in Nirma are more varied and extensive. Thus if that's your basis for selection then that should be your pick. If the curriculum is in question then they have a similar curriculum with yearly moot courts.
