**For
the National Science Olympiad ( NSO ), there would be one common
question paper for both medical and non-medical students of classes 11
& 12.**

The NSO paper would have 4 sections. Section 1 and section 2 on physics and chemistry would be compulsory for all students. Students may choose between section 3 on biology or section 4 on non biology questions and answer as per their stream.

The above is expected to simplify and stream line registrations of class 11 and class 12 students. The earlier practice of having separate papers for biology and non-biology students is being discontinued.
