I chose computer science because I wanted to. In our class, we had a total of 48 students. And the staffs available were 9. All the teachers were qualified in both NET and SET and completed their Ph.D. The method of teaching is absolutely fine. Even if you have doubts about some topics they are ready to explain them to you separately. Internal exams are conducted a month before semesters and it is not that difficult if u learn and write the exam.
