12th mai ek name se exam dene ke bad fir se 10th and 12th dusre name se dene par iit ka exam dene milega
Hello,
If you are change your name in officially then it's okay. You can apply for IIT with your changing name and new examination result. If you are not changing your name by officially then you can't get admission in IIT with different name. I think you can understand what i said.
All the best.
