Hi, the information that you have given is a little incomplete. You can give JEE mains if you want admission is any other state than yours for Mechanical Engineering and you can give your state level CET if you want to get admission in colleges that are in your home state. The ranks differ as per your college and the caste. I however recommend you to keep a set goal of 10,000 to 30,000 for government colleges and private colleges usually extend up to 1,00,000. All the best!
