It doesn’t matter in which branch of engineering you are in, every branch has some theory sessions and practical sessions. It is important to take the help of technology to implement theoretical concepts practically.
You can definitely carry a laptop in the class but you might not be allowed to use it during lectures. You need to take prior permission from the faculty if you want to operate it for programming or learning a lesson. If anyone denies you to do so, you can directly contact the HOD. Other than that, you can use it during lunchtime for practice sessions.
LNCT has well-established labs for each branch and they are updated with the latest software. You can utilize the laboratories easily if you don’t have a laptop.
