Hi

I am guessing that you are asking about B tech biotechnology.

Actually, not  all colleges offers B tech biotechnology to Biology students ( without maths in 10+2)

For example,

NITs offer btech biotechnology, like NIT Calicut NIT Durgapur etc but you cannot get admission for B tech biotechnology in NITs as they offer admission through jee Main and it is compulsory to have studied mathematics in 10 + 2 to be eligible for JEE Mains. So, you cannot get admission in any Engineering College even for Biotechnology which provides admission through only JEE mains as to be eligible for JEE main it is mandatory to have  studied maths.

Colleges like VIT offers B tech biotechnology to Biology students.

For example,

To be eligible  VITEEE exam for btech biotechnology , one needs an aggregate of at least 60% in Physics, Chemistry, Mathematics/Biology in 12th board exam or 50 % in aggregate of physics chemistry maths/ biology is belongs to SC or St category

So, both Math and Biology students are eligible for B tech biotechnology in VIT .So being a Biology student you can pursue BTech biotechnology in VIT

Even chandigarh University  allows students with only Biology in there B tech biotechnology.

To be eligible for btech biotechnology in chandigarh university, one needs to pass 12th from a recognised board with atleast 50% marks in aggregate with Physics & Chemistry with either Mathematics or Biology

You can check the same at its official page at

So, you give Entrance examinations like VITEEE for VIT and CUCET for chandigarh university which are one of the  best colleges for your btech biotech without biology in 10+2.

Thank you
