Hi Akshat

According to previous year trends, a score of 160 would generally translate to a rank of around 5000. However please note that this is only an estimation, and can vary hugely with the difficulty of the actual exam. Also, I would suggest you in this regard, that when you attempt mock tests, give yourself 20-30 minutes lesser. In actual exam, much of the time is lost for most people by panicking and under exam pressure. Good luck! :)
