Hello dear candidate,
Guru Nanak dev university enrols students based on entrance exams taken by the university. The entrance exam will hold in offline mode this year. So, you need to prepare well for the examination as it will determine your seat.
So, the pattern is simple in the examination paper. There are MCQ based questions majorly asked from the topic in class 12th and some little parts from the course. As you are opting for BCA then you should prepare some basic questions especially on computer Languages.
Eligibility: Students who have passed class 12th with a minimum of 40% marks from a recognized board are eligible for participating in the entrance.
