About B.Tech
A Bachelor of Technology (B.Tech) is a four-year undergraduate engineering program for students who have completed Class 12 with Physics, Chemistry, and Mathematics (PCM). It builds a foundation in core engineering principles before moving into a specific branch of specialization, blending classroom theory with labs, projects, and internships.
Admission to most reputed institutes in India is through national or institute-level entrance exams such as JEE Main, JEE Advanced, GATE (for M.Tech/lateral routes), and specialized exams like NATA for architecture. The program typically covers common engineering fundamentals in the first year, followed by branch-specific coursework and a final-year major project.

B.Tech Entrance Exams
Admission to engineering programs in India runs through a set of national and institute-level entrance exams. Each one is accepted by a different set of institutes, so the right exam to prepare for depends on which colleges you're targeting. Here's a quick look at the exams that matter most.
JEE Main
Joint Entrance Examination – Main
The primary gateway to NITs, IIITs, and other centrally funded technical institutes, and the qualifying stage for JEE Advanced. Tests Physics, Chemistry, and Mathematics from the Class 11–12 syllabus.
JEE Advanced
Joint Entrance Examination – Advanced
Open only to top JEE Main qualifiers, this is the sole entrance exam for admission to the IITs. Known for its conceptual, application-heavy question style across PCM.
IISER
IISER Aptitude Test
The entrance route into the 5-year BS-MS dual degree program at the IISERs, focused on core science subjects for students aiming at a strong research-oriented foundation.
