As you know that from last year the percentile system come into play. So let me tell you about some earlier stats so earlier if someone scored 180 and above in ji he or she can get CS easily. If someone is ko 120 that he can get electronics mechanical or electronics and if someone score above 90 that he could get civil. But as you know that now it is percentile system so you have to work more hard as you will get less percentile on more marks. So as per me you should assume at least 20 to 30 marks above then these as your target. All these stats are considering that you are from general category and a male. Hope you get admission to your desire branch btech. Wish you luck.
