Exams are total 8 semesters in span of 4 years of btech for 1st year it's same to every department or branch and two mid term examinations for each semester and labs for one mid only followed by midterm 2

The frequency and timing of exams along with your perspective on their difficulty level The area I want to suggest is that they have to clean the class boards properly some some times the bord is not visible

The computer science and engineering is the good course according to me, but it's totally depends on your interest and your performance in that course. Other courses are also good but they are hardware where you need to work physically, but in software you don't need to work physically. This is an advantage.
