Hi

Without maths, being a PCB student you cannot pursue engineering/btech courses like Btech computer science, mechanical, electrical, IT etc.

With PCB you can pursue only btech like Btech biotechnology.

But again,

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.

For your reference,

Jee main eligibility criteria is given below-

---------------------------) Qualification required :- to be eligible  for JEE mains you need 10+2/equivalent qualification from a recognised board.

For complete jee main eligibility criteria, checkout:-

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 etc
