There is nothing as such, anyone who is enthusiastic about coding and willing to learn new things for their professional betterment can enroll.

No, this is kind of pure offline training where we train on a full-day basis in the institute with live projects. No online classes will be conducted.

It will contain the Full Stack development course, a set of live projects that you will be working on, after the completion of the course at the end, you will receive a certification and placement assistance.

Strong Mentorship as mentioned earlier with a good friendly atmosphere, which will ensure you get practical knowledge on the subject.
