Hello dear student,

To qualify the eligibility criteria to appear in nest 2020 exam. Candidate need to complete their 10+2 exam from a recognised board.

Also candidate must need to have mathematics as a subject in their class 12th while the other three subjects are physics chemistry biology or life sciences. so as you asked you belong from non biology stream but looking at the eligibility criteria it is clear student must need to come from a biology background and they must have mathematics India class 12th otherwise they are not eligible.

There are many other criterias also other than these but as you are specifically asked for the above I have mentioned above only.

Thank you
