National Science Olympiad (NSO)

Official Website : nso

The National Science Olympiad is organized every year to motivate students to strive for better and deeper understanding of scientific facts and data and to enhance their reasoning, analytical and problem solving skills All school students from class 2nd onwards are invited to participate in this unique contest that tests their understanding, level of knowledge, applications and power of reasoning.

NSO Exam Date
During 2012-13 the first Round of NCO exam will be held on 22nd & 29th Nov 2012. at participating schools.
