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 having questions of physics and chemistry would be compulsorily to be attempted by all students. Students have an option to choose between section 3 on biology or section 4 on non biology questions and answer as per their stream.

The streams to be taken should be pre-clarified. The earlier practice of having separate papers for biology and non-biology students is being discontinued.

No more confusion, prepare with fully solved previous years questions for all Olympiads: NSO, NCO, IMO, and IEO for all classes.
