B.Tech – Bachelor of Technology

Course Overview

B.Tech (Bachelor of Technology) is a 4-year undergraduate degree in engineering and technology. The course combines classroom learning, practical training, laboratory work, projects and industry-related skills.

Students can select different engineering branches according to their interests, such as Computer Science & Engineering, Information Technology, Mechanical Engineering, Civil Engineering, Electrical Engineering, Electronics & Communication Engineering, Artificial Intelligence and Data Science, etc.

Course Duration

• 4 years
• Usually divided into 8 semesters
• Some universities may offer lateral entry options for eligible diploma holders, where applicable.

Eligibility

Generally, students should:

• Pass Class 12 / 10+2 from a recognised board.
• Have Physics and Mathematics as compulsory subjects.
• The third subject may vary by university, commonly Chemistry / Biotechnology / Biology / a technical vocational subject.
• Minimum marks and subject requirements vary by university and branch.
• For admission through national-level counselling, additional eligibility rules may apply. JoSAA publishes institute-specific eligibility and restrictions. 

Approximate Fees

B.Tech fees vary significantly according to the university, branch, category and facilities.

General indicative range:

• Government institutes: approximately ₹1 lakh–₹3 lakh per year
• Private universities: approximately ₹1.5 lakh–₹5 lakh+ per year
• Hostel, examination, development and other charges may be additional.

For example, NIT Delhi's 2026–27 B.Tech first-semester fee varies by income/category; the published day-scholar total ranges from ₹51,700 to ₹1,14,200, depending on the applicable fee category.

At VIT, the 2026–27 B.Tech tuition fee varies by programme group and fee category; the published figures range from approximately ₹1.73 lakh to ₹4.90 lakh per year before considering the applicable scholarship category.

Therefore, students should always check the latest fee structure of the selected university before admission.

Admission Process

The admission process depends on the university and state.

Common routes include:

1. Complete Class 12 with the required subjects.
2. Appear for the required entrance examination, if applicable.
3. Obtain the examination rank/score.
4. Register for counselling or university admission.
5. Select the preferred branch and college according to eligibility, rank and seat availability.
6. Complete document verification.
7. Pay the admission fee and confirm the seat.

For IITs, NITs, IIITs and other participating government-funded institutes, JoSAA manages the central seat-allocation process. For 2026, JoSAA covers 23 IITs, 31 NITs, 26 IIITs, IIEST Shibpur and other participating institutes.
