What is the pass mark in Osmania University for the BE 1st SEM?

One of my friends had studied at Osmania University.

In the latest CBCS system that was being introduced in the year 2016, you must get 40% of the total marks. In other words, if you get a total of 40 marks including your external and internal in all of the subjects, then you will pass the semester.

Earlier, that is, before 2016, students had to score a minimum of 28 marks in the external examination to pass the semester.

The current rule is that, if you get 40 marks overall (Internal + external) then you will pass whereas the internal assessment is on 30 marks.
