B.Tech is a four-year undergraduate engineering program requiring students to have completed class 12 with a science background, particularly in physics, chemistry, and mathematics. Admission is based on performance in engineering entrance exams like JEE Main and BITSAT, and the program emphasizes practical, skill-based training alongside theoretical knowledge. While B.Tech and B.E. courses are similar in India, B.Tech is generally more application-oriented, focusing on technological skills and including components like internships and industrial visits.
