Dear Aspirant, 

Local rank is used to calculate the probability of securing seat better. 

The local rank will help give better analysis of the position among the local students .

The probability of securing seat depends on factors like branch ,category, reservations. Hence having not provided such data it is hard to estimate. Therefore use the predictor tool:

Hope this helps. 

Good luck.
