Hello Riddhi.

With 81 marks in SLAT it is very difficult to get a seat in Symbiosis Noida. As per previous year cutoff trend scoring 95 to 110+ marks in SLAT would have been helpful in getting BA LLB or BBA LLB in Symbiosis Noida. The cutoff may differ from year to year. But apply for other colleges too. 

Hope this is useful.

Thank you.
