Some universities also hold separate exams for diploma holders applying through lateral entry. In a few cases, JEE Main scores may also be accepted for this route.
BTech Admission Process
The BTech admission process in India can vary depending on the type of college and the mode of study. Most students follow the standard entrance exam route, but there are also options for direct admission and online BTech programs.
1. Admission through entrance exams
This is the most common way to get into a BTech course.
Step 1 – Entrance exams
First, students must appear for a relevant BTech entrance exam. Popular exams include JEE Main (for NITs, IIITs, and other top colleges) and JEE Advanced (for IITs).
Many states also conduct their own exams like MHT CET, KCET, AP EAMCET, and TS EAMCET.
Private universities like VIT, SRM, and BITS hold their own tests such as VITEEE, SRMJEEE, and BITSAT.
These exams usually take place between April and June each year.
Step 2 – Application process
After qualifying the entrance exam – students must apply to the colleges they are eligible for. Applications are usually submitted online through college or government portals.
Step 3 – Counselling
Once results are out, students take part in a counselling process. They choose colleges and specializations based on their exam rank. This is where preferences are filled.
Step 4 – Seat allotment
Based on rank and choices – students are allotted a seat. This happens through centralized counselling (like JoSAA for IITs and NITs) or state/university-level systems.
Step 5 – Admission confirmation
Once a seat is allotted, the student must visit the college for document verification and pay the BTech course fee to confirm admission.
2. Direct admission without entrance exam
Some private colleges offer BTech seats without entrance exams.
- Management quota – A fixed number of seats are reserved for direct admission based on Class 12 marks. A separate fee or donation may apply.
- Merit-based direct admission – A few colleges admit students directly based on their 12th marks. Some may also conduct interviews or skill tests.
- These options are common in private colleges, but not available in top-tier institutes like IITs or NITs.
3. Admission to online BTech programs
Online BTech programs follow a different process –
- Eligibility check – Students must have completed 10+2 with PCM subjects. Some programs may also consider GPA or past academic performance.
- Application process – Students fill out an online form and upload documents like mark sheets and ID proof.
- Entrance test or interview – Some universities may hold a basic test or online interview. Others may skip this step and focus on academic background.
- Admission confirmation – If selected, students get an offer letter. They must pay the admission fee to confirm their seat.
- Enrollment and classes – After completing formalities, students get access to the Learning Management System (LMS) where they can attend online classes, submit assignments, and appear for exams.
