B.Tech (Bachelor of Technology)
What is B.Tech?
Bachelor of Technology is the full form of B.Tech and it is one of the most popular engineering programmes in India. It is an engineering degree which is awarded to those who have completed the undergraduate course in B. Tech. A degree in Bachelor’s of Technology is often considered as a gateway to the field of engineering. The duration for completing the Bachelor’s of Technology is between three to four years, depending on the country and the institution. In India, the duration to complete the degree is around four years, spread over eight semesters.
Skill-sets required for B.Tech?
It is important for an engineer to not only possess great technical skills but also social and emotional intelligence. Compassion, empathy, insights, knowledge, logic, and skill must all combine. If the person has a curious, creative, and innovative mind who likes to dig deeper into problems and apply logical thinking and reasoning then engineering is a profession they could look into. B. Tech, through its four-year full-fledged learning path, teaches prevalent and useful technical skills along with interpersonal skills. It develops a team spirit in students, helps them to be more accurate and precise, provides a platform to improve their communication skills, and teaches them resilience and self-discipline.

Types of B.Tech
Bachelor of Technology (B.Tech) is in itself a type of technology course. There are no other types of B.Tech programmes. The programme is an undergraduate degree course which will help the students to gain specialization for better career opportunities in the future.
For admissions into B.Tech. programmes, the students will have to qualify the 10+2th examination from the science stream from any board. If a student is interested or wants to get into a B.Tech. the programme, it is advised that he or she has the PCM (Physics, Chemistry, and Mathematics) group as the main subjects, as individuals from this subject group are preferred for the programme.
The above-mentioned way is the regular method to enter the programme, however, there is a second method which is by the way of a lateral entry scheme. With the help of the lateral entry scheme, students who have done a diploma in engineering domains are eligible to enroll in a Bachelor of Technology programme in the second year. The lateral entry scheme is meant for those students who have joined or are doing diploma courses after 10 or 10+2 in various technical trades and aim to gain admissions to B.Tech. programmes in the second year, offered by various engineering institutes and colleges across India.
In short, the basic eligibility to gain admission for Bachelor of Technology or B. Tech. programmes are that a candidate should have completed 10+2 in Physics, Chemistry, and Mathematics (PCM) or should have done a three-year diploma programme in any engineering stream to gain admission through lateral entry in the second year.
Engineers are some of the highest-paid professionals across the world, especially in western countries, so it is naturally a dream for many in India to make a career in the engineering field. The aspiration to become high-earning professional drives many to take admission in engineering courses. In India, becoming an engineer is something most of the science students strive for. Therefore, the competition to gain admission into the top engineering institutes of India is quite intense.
To ensure that only the best are granted admission, there are various entrance examinations or tests for Bachelor of Technology or B.Tech. courses offered in institutes across the country.
Entrance examinations such as JEE Main, JEE Advanced, BITSAT, AP EAMCET help the institutes to screen students according to merit. These entrance examinations test the prospective engineering students on the basics of engineering, which is in line with their 10+2 syllabus. Based on the performances in the above-mentioned entrance examinations, individuals are selected and further screening processes take place, before finally gaining admission to B.Tech. programme.
Top B.Tech Exams
There are various entrance examinations for gaining admission to B.Tech. programmes that are offered by various institutes. The entrance examinations can be divided into national level entrance examinations, state-level entrance examinations and institute specific examinations. Here, we are going to divide and explain the entrance examinations according to national, state and institute specific examinations.
National Level Examination for B.Tech
National level examinations are those entrance examinations that are organised and conducted to select the right aspirants for admissions into national level engineering public institutes. There are several private institutes as well which accept and consider scores in these examinations and these entrance examinations also form a part of their admission processes for their B. Tech. courses.
The two important national entrance examinations are as follows:-
JEE Main – Joint Entrance Examination (Main)
JEE Main is a national level engineering entrance examination that is used for selecting and screening those individuals who are looking to gain admission to B.Tech. courses in institutes such as National Institutes of Technology (NITs), Indian Institutes of Information Technology (IIITs) and Government Funded Technical Institutes (GFTIs). However many state and private colleges also accept JEE Main scores for admissions. JEE Main entrance examination also acts as an eligibility test for JEE Advanced
JEE Advanced – Joint Entrance Exam (Advanced)
The JEE Advanced is the screening examination for students seeking admission into Indian Institute of Technology (IITs).. Those who come under the top 2,50,000 candidates in JEE Main will be termed eligible to attempt JEE Advanced..
State Level Examinations for B.Tech
Similar to national-level examinations, several states conduct state-level entrance examinations for B.Tech. courses offered in government institutes. Again, several private colleges accept scores of these entrance examinations. Some of the state-level entrance examinations are mentioned below.
WBJEE – West Bengal Joint Entrance Examination
West Bengal Joint Entrance Examination is conducted by the West Bengal Joint Entrance Examinations Board (WBJEEB). It is conducted for those students who are interested in gaining admission into the undergraduate engineering courses offered by the participating institutes.
MHT CET - Maharashtra Common Entrance Test
State Common Entrance Test Cell, Maharashtra conducts MHT CET to provide admissions into the B.Tech courses offered by the participating institutes. The exam is held as a computer based test and the syllabus consists of 11th and 12th standard topics.
Institute Specific Examinations
Apart from government institutes, several private institutes offer B. Tech. programmes. Several private institutes conduct their entrance examinations for admission purposes.
BITSAT – Birla Institute of Technology and Science Admission Test
As the name suggests, BITSAT is conducted by Birla Institute of Technology and Science, Pilani for students who are interested in gaining admission in B.Tech programmes taught at BITS Pilani and other campuses such as BITS Goa and BITS Hyderabad.
