The Indian institutes of technology (IITs), are a group of sixteen autonomous engineering and technology-oriented institutes of higher education established and declared as institutes of National importance by the Parliament of India. The IITs were created to train scientists and engineers, with the aim of developing a skilled workforce to support the economic and social development of India after independence in 1947. Each IIT is an autonomous university, linked to the others through a common IIT Council, which oversees their administration. They have common admission procedure for undergraduate admissions, called joint entrance examination (popularly known as IITJEE) to select around 10,000 undergraduate in an year.

IIT-JEE is one of the toughest and most coveted Engineering Entrance Exams in the world. The syllabus of the examination is based on topics which are covered by the CBSE Board Examination (AISSCE) and the ISC Board Examination, though all topics of the AISSCE and the ISC are not included in the JEE syllabus.

The B.Tech eligibility criteria is the same across the country, and the basic qualification required to join B.Tech course in India is as follows –

-> For pursuing B.Tech course, one must pass Class 12 in Science stream. The students must have Chemistry, Mathematics, and Physics as the subjects in Class 12. Students who have studied only these subjects in Class 12 are treated eligible for B.Tech admission.
-> In addition, students must score at least 50% of marks in Class 12 to be eligible for B.Tech admission in engineering colleges across the country. However, students belonging to reserved categories such as SC/ ST will have the relaxation of up to 5% in the minimum qualifying marks.
-> For some of the engineering streams like Biomedical Engineering, students must have studied Biology as one of the subjects in Class 12.

JEE Advanced score is mandatory to get B.Tech admission in Indian Institutes of Technology (IITs). IIT B.Tech admission process involves multiple stages, and important details about the B.Tech admission process of IITs are explained below:

Stage 1 – Qualify JEE Main: IIT B.Tech aspirants must qualify JEE Main exam conducted National Testing Agency (NTA) to clear the first stage of IIT B.Tech admission process. Not all the qualifiers of JEE Main will be declared eligible for the second stage of the admission process. Top 1,50,000 to 2,00,000 qualifiers of JEE Main will be shortlisted for the second stage of the admission process.
Stage 2 – Qualify JEE Advanced: Candidates who have been shortlisted for the second stage of IIT B.Tech admission process must qualify JEE Advanced exam conducted by IITs. Without qualifying JEE Advanced, the candidates could not get admission in IITs.
Stage 3 – Participate in JoSAA: JEE Advanced qualifiers must register for centralised admission process for IITs conducted by JoSAA (Joint Seat Allocation Authority). After the announcement of JEE Advanced results, IITs will release opening and closing ranks for IIT B.Tech courses. The candidates must exercise the options depending on their rank. If the candidates secure the opening or closing rank prescribed by respective IIT, he/ she will get admission.
Stage 4 – Accept the Admission Offer and Fee Payment: After securing the admission, the candidates must download provisional admission letter from the JoSAA website and fee payment e-challan. The candidate s must pay the fee acceptance fee online. Stage 5 – Verification of Documents: After the payment of seat acceptance fee, the candidates must report to the prescribed reporting centre for documents verification. Later, the candidates must visit the respective institute within the stipulated date.

JEE Main score is required for B.Tech admission in National Institutes of Technology (NITs). NIT B.Tech admission process is different from IIT B.Tech admission process, and the important details about the B.Tech admission process of NITs are explained below:

Stage 1 – Qualify JEE Main: NIT B.Tech aspirants must qualify JEE Main exam conducted National Testing Agency (NTA) to clear the first stage of NIT B.Tech admission process.
Stage 2 – Participate in JoSAA: JEE Main qualifiers must register for centralised admission process for NITs conducted by JoSAA (Joint Seat Allocation Authority). After the announcement of JEE Main results, NITs will release opening and closing ranks for NIT B.Tech courses. The candidates must exercise the options depending on their rank. If the candidates secure the opening or closing rank prescribed by respective NIT, he/ she will get admission.
Stage 3 – Accept the Admission Offer and Fee Payment: After securing the admission, the candidates must download provisional admission letter from the JoSAA website and fee payment e-challan. The candidate s must pay the fee acceptance fee online.
Stage 4 – Verification of Documents: After the payment of seat acceptance fee, the candidates must report to the prescribed reporting centre for documents verification. Later, the candidates must visit the respective institute within the stipulated date. The candidate s must pay the fee acceptance fee online.
