In India, admission to B.Tech programs is granted solely through entrance exams administered at the state, national, and university levels. A bachelor of technology, or B.Tech, is a four-year undergraduate engineering program that prepares students to conduct research on cutting-edge and emerging technologies and to acquire knowledge and abilities in the field. To develop knowledge in a certain field of technology, the course is separated into several specializations, such as B. Tech mechanical engineering or B. Tech biotechnology.
