hope you got your answer 

Hello,

You can give any exam such as JEE, VITEEE, BITSAT etc. According to the college you want to take admission in you can choose the exam. But whichever exam you give you have to start with first year of B.Tech course again. You can take admission in any college like IIT, NIT etc. after you clear the entrance.
