The Royal Society of Chemistry has released the results of Round One in this year's Chemistry Olympiad. 5,822 students entered the competition, which is primarily aimed at high-achieving Upper Sixth students of Chemistry in the UK. The Harrovian cohort was awarded nine Gold Certificates, 14 Silver and 14 Bronze. A Gold Certificate places the candidate in the top 458 of all those who sat the examination. Out of our nine gold winners, three are in the Lower Sixth. Our highest-scoring student, Callum McLean, has been invited as one of only 27 students to Round Two of the competition, which will be held at Cambridge University from 1 to 3 April 2016. During this next round, the Olympiad committee will choose the team of four to represent the UK in the international finals in Georgia during the summer. These results are the best ever obtained by Sixth Form chemists at Harrow.
