Can i get admission into SIT Pune with 81 percentile in JEE mains ?

If you look at the previous year JEE Main cutoffs for SIT Pune, ranks between 13000 to 30000 are sufficient for the admission. 

81 percentile jee main translates to rank in between 230000 – 260000. 

Therefore on 81 percentile there are no chances of getting SIT Pune. For the admission you need to crack jee main with somewhere around 98-99 percentile. 

You have another option that you can sit for the SET exam which is conducted by Symbiosis pune itself for the admission.
