The answer is:
It depends on the university and its admission rules.
Some B.Tech Biotechnology programmes are designed around mathematics and engineering fundamentals, while particular institutions may have different subject requirements for admission.
Even where the admission pathway permits students without advanced mathematics, students should understand that an engineering programme can still involve quantitative subjects.
For example, current IIT Delhi curriculum information includes calculus, linear algebra and differential equations, probability and statistics, programming and engineering subjects alongside biological sciences.
Therefore, students should check both:
- Admission eligibility
- Actual course curriculum
These are not always the same thing.

Step 3: Appear for the required examination
If an entrance examination is required, students need to meet the relevant registration deadline and examination requirements.
Step 4: Participate in counselling or selection
Eligible candidates may need to participate in counselling, choice filling, seat allocation or an institutional selection process.
Step 5: Complete admission formalities
After receiving an offer, students generally need to submit documents, pay applicable fees and complete verification.
Because admission policies can change, students should rely on the current official notification rather than an old admission article.
B.Tech Biotechnology Entrance Exams
There is no single entrance examination that applies universally to every B.Tech Biotechnology programme.
