Should you pick B.Tech Biotechnology at Adhiyamaan College of Engineering?
This course suits students who like biology and lab work and plan for higher studies or a lab career.
Pick it if:
You want biotech internships close to home: the department has tie-ups with Biocon Academy in Bengaluru and Genewin Biotech in Hosur for internships and projects.
Your OC rank is near the 2025 close: the closing rank got easier three years in a row, from 103,717 in 2023 to 171,328 in 2025.
You are the first graduate in your family: the state cuts INR 27,500 from your tuition fee every year on a government quota seat.
Skip it if:
You want a lab job right after the degree: the biggest recruiter on the last list, Episource Healthcare, hired 10 students for healthcare data work.
You want a high first salary: this branch averaged INR 2.8 LPA, which is much lower than the college median of INR 3.75 LPA.
You want a big class: TNEA filled only 22 of its 35 general seats in this course in 2025, so the batch is small.
You need the hostel fee in writing before you join: the college does not publish it, so ask the hostel office before you pay anything.
Counsellor's advice
If TNEA gives you this seat and you plan on an M.Tech or a lab career, take it. If you want a quick IT job, keep the IT branch here above it in your choices.

In short
Muthayammal costs INR 20,000 less, pays a higher median and has an easier closing rank, but its Biotechnology course is not NBA accredited. If the NBA tag matters to you, keep Adhiyamaan above it; if pay matters more, list Muthayammal first.
In short
Erode Sengunthar places more of its graduates and costs INR 20,000 less, with a slightly easier closing rank. If you want internships near Hosur and Bengaluru, keep Adhiyamaan first; if you live near Erode, list Erode Sengunthar above it.
In short
SV Hi-Tech placed almost its whole graduating batch, but that batch is small and its closing rank is tougher. If your rank clears both, either is a fair pick; if it clears only Adhiyamaan, take this seat.
In short
Paavai pays a higher median and costs INR 20,000 less, but its closing rank is much tougher. If your rank clears Paavai, compare the two campuses before you choose; if it does not, Adhiyamaan is the seat within reach.
Fees and pay can change. Check each college site before you decide.
FAQs on Adhiyamaan College of Engineering B.Tech Biotechnology
Straight answers to what students ask before they decide.
Is B.Tech Biotechnology at Adhiyamaan worth the fee?▾
Yes, on a government quota seat. The full fee is INR 2.40 Lakhs and this branch averaged INR 2.8 LPA on its last placement list, so the fee comes back in the first working year. A management quota seat costs INR 3.68 Lakhs, so check the EMI line in the fee block before you take a loan.
What job will I get after this course?▾
Most offers on the last list came from healthcare data and IT companies, not from labs. Episource Healthcare hired 10 of the 40 placed students, and Biocon hired 2. If you want a lab job, use the Biocon Academy and Genewin Biotech tie-ups for internships from year 2.
Who should not take this course here?▾
Skip it if you want a high first salary or a big IT recruiter list. This branch averaged INR 2.8 LPA, much lower than the college median of INR 3.75 LPA. If a quick IT job is your goal, put the IT or CSE branch here above Biotechnology in your TNEA choices.
Should I take this seat if my rank is just inside the closing rank?▾
Yes, the risk is lower here than in most branches. The OC close got easier three years in a row, to 171,328 in 2025, and only 22 of 35 general seats were filled. Still keep two or three safer choices above it, and use the rank checker above for your community.
Is this course good for higher studies and research?▾
Yes, if you plan for it early. The department has 16 labs, from molecular biology to downstream processing, and you can do your final project there. Most lab and research jobs in biotech ask for an M.Tech or M.Sc, so prepare for GATE from year 3.
Should I pick Biotechnology or IT at this college?▾
Pick Biotechnology if you like biology and plan on higher studies or lab work. Pick IT if you want a software job soon after the degree. Biotechnology averaged INR 2.8 LPA on its last list, so the pay gap is real. Choose on the work you want to do for years, not only on the first salary.
Will I get a job if I am not in the top of the batch?▾
Most likely yes, but expect an IT or healthcare data role first. The last list placed 40 students through 21 companies, so most offers came from mass recruiters. Keep your CGPA steady, finish an internship before year 4 and sit every campus drive the placement cell lists.
Is a management quota seat worth it for this course?▾
Only if you cannot get a government quota seat through TNEA. A management quota seat costs INR 3.68 Lakhs against INR 2.40 Lakhs, and the pay after the course is the same. Try every TNEA round first, as only 22 of 35 general seats were filled in 2025.
How do I get admission to this course?▾
Register on TNEA, which ranks you on your Class 12 Maths, Physics and Chemistry marks out of 200. Fill this college, code 2601, and Biotechnology in your choices. Confirm the allotment online and join by the date TNEA gives, or you lose the seat.
What is the full fee for the course?▾
The full 4-year fee on a government quota seat is INR 2.40 Lakhs, which is tuition plus the development fee. A management quota seat costs INR 3.68 Lakhs. Hostel is extra and the college does not publish it, so ask the office before you pay.
Can I get a scholarship for this course?▾
Yes, two state schemes help. The post-matric scholarship pays the full tuition fee for SC, SCA and ST students with family income up to INR 2.5 Lakhs. The first graduate concession cuts INR 27,500 a year. Use the scholarship calculator above to see your total.
Do I get the caution deposit back?▾
Yes. The caution deposit of INR 5,000 is refundable and comes back when you leave the college. Keep the fee receipt safe, because the office asks for it when you claim the refund.
The college offers admission through TNEA Counseling based on 12th-grade cut-off marks, where students select their preferred college in rounds. It is valued for affordability and proximity to Bangalore. Each department is staffed with at least 10 faculty members, most having PhDs, who teach industry-related subjects. As an autonomous institution under Anna University, the college features excellent infrastructure and a library, with technically driven teaching and frequent unit exams for effective learning.
The annual fee is 60,000 INR for counseling students and 95,000 INR for management quota students, with a sports quota available for fee reduction. The college excels in placements, with 85% of students securing jobs annually, supported by companies like TCS, CTS, and Wipro. Placement preparation begins in the third year, and students can engage in internships and projects. Although many scholarships are available, specifics were not detailed in the review.
