Hello Rahul, 

For admission in RTU Kota, one must apply for REAP counselling. It has a method to prepare a merit list in which Jee Mains score holds more priority than class 12th score. For admission in RTU Kota, one must secure a very good rank in Jee mains too and the 12th score should also be good but if one is only applying through class 12 th score then you really need your score in 90s and even then also, you are on the verge of getting Computer Science there.
