Hi Amit! With 35 percentile, it is indeed difficult to get a call from Symbiosis institutes. For SIOM Nashik, the cutoff would range from 70-75 percentile. If you have appeared for other MBA entrance exams, you can take admission on the basis of those scores. You may try using the SNAP Pathfinder tool to check if there is any chance to get a call from any of the SNAP participating institutes with your percentile:
