Hi, I went to college at CBIT, which is located along the route to your campus. There are no direct buses from Secunderabad to your campus. I can give you the bus numbers and routes you need to take.
You first need to get to Mehidipatnam, which you can do by taking any bus number 5. The buses are located near the front exit of the railway station. When you reach Mehidipatnam on bus number 5, you can find the State Bank ATM by asking around as most people are helpful. Opposite the ATM, there is a bus stop where the Shankarpally buses stop. Take that bus and it will take you directly to your campus.
Please be cautious of two things: it may be difficult to find a ride through Uber or Ola to your campus. Additionally, from 8:30 am to 10:30 am, the buses tend to be overcrowded with students, making it challenging to board.
