Eligibility for BTech in India
Eligibility for BTech depends on the admission route chosen. There are three common pathways.
1. Regular Admission (After Class 12)
Students must complete Class 12 with Physics, Chemistry, and Mathematics. Most colleges require 50–60% marks, while top institutes like IITs may require 75% in PCM subjects. Some branches such as Biotechnology may also accept Biology students. Entrance exams like JEE Main, JEE Advanced, WBJEE, or VITEEE are usually mandatory.
2. Lateral Entry (After Diploma)
Diploma holders with a three-year engineering diploma can join BTech directly in the second year. The diploma must be from a recognized institute, with a minimum of 50% marks in most cases.
3. Online BTech Programs
For online BTech programs, students must have passed 10+2 with Mathematics. There is usually no age limit, and entrance exams may or may not be required depending on the institution.
BTech Entrance Exams
Most top engineering colleges in India admit students through entrance exams conducted at different levels.
National-Level Exams
- JEE Main: Used for admission to NITs, IIITs, and GFTIs
- JEE Advanced: Required for admission to IITs; only JEE Main qualifiers can appear
University-Level Exams
Private universities conduct their own exams, such as VITEEE (VIT), SRMJEEE (SRM University), and BITSAT (BITS Pilani).
State-Level Exams
States conduct entrance tests for local colleges, including WBJEE, MHT CET, KCET, AP EAMCET, TS EAMCET, and COMEDK UGET. More than 7.25 lakh students have registered for MHT CET 2026.
Lateral Entry Exams
Some universities hold separate entrance tests for diploma holders seeking lateral entry into BTech programs.
BTech Admission Process
The BTech admission process varies by institution but generally follows these steps.
Admission Through Entrance Exams
- Entrance Exam: Students appear for exams like JEE Main, JEE Advanced, or state/university-level tests.
- Application: Eligible candidates apply online through official portals.
- Counselling: Students select colleges and branches based on rank.
- Seat Allotment: Seats are allotted through centralized or state-level counselling.
- Confirmation: Admission is confirmed after document verification and fee payment.
Direct Admission Without Entrance Exam
Some private colleges offer management quota or merit-based direct admission based on Class 12 marks. These options are not available in IITs or NITs.
Admission to Online BTech Programs
Online programs involve eligibility checks, online applications, possible interviews or tests, and final enrollment through a Learning Management System.
