NIT Warangal First Semester Results

I have given exams of B.Tech First Semester Examination of NIT Warangal. Some one informed me that the result of First Semester Examination of B.Tech is declared and I can check it online on its official website. But when I was visited website, there is no notification for result of B.Tech First Semester result. So provide contact information of exam office of NIT Warangal.
