Hi

Yes, you can do B tech biotechnology even if you are a PCB student i. e you don't have maths in your 10+2

but yes not all the college offers B tech biotechnology to Biology students.

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 12tg 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
