Hello,
Having not opted for Mathematics in your Class 12th, you are not eligible for pursuing B.Tech in Agricultural Engineering, because it is mandatory to have Mathematics, Physics and chemistry in Class 12 as a main subjects of education.

But there is another option that is after you have completed your Class 12th with PCB, you can go for B.Sc. in Agriculture degree course, only if you are interested .

Hii!
The eligibility criteria for agricultural engineering states that the candidate must have passed class 12th with PCM as main subjects and either one of the following - biology/ biotechnology/ agriculture from a recognised board of education. So, if you only have PCB, you are not eligible.
Hope this helps.
Good luck!
