Hi Srini,

what course have you applied for? If its for graduation. Alongwith with entrance test they have GD and PI. The entrance exam is of moderate difficult. There is usually no negative marking and since questions come from General awareness also, its important you brush through current affairs and practice verbal as well as non verbal reasoning. LLB entrance is of 200 marks and also tests legal aptitude. If possible try getting past papers from somebody who has appeared before, many of those available arent authentic. 

Hope this helps! Feel free to ask further
