英国化学奥赛

The UK Chemistry Olympiad

Certificate

英国化学奥林匹克竞赛2023第一轮, 来自950所学校的11838名学生参加了比赛--创造了两者的新纪录。铜奖、银奖和金奖争夺战中，72%的参赛学生获得了奖项，再次超过了去年的成绩。今年的试卷比去年难度有所降低，这意味着与去年相比，学生需要取得更高的分数才能获得每个奖项。学生必须达到14-23分才能获得铜奖，24-37分才能获得银奖，38分或以上才能获得金奖。

2023年的论文涉及的主题包括火箭燃料、电负性、氨基酸复合物、汽化和奶酪。电负性是一个及时的话题，因为在2022年是莱纳斯-鲍林提出电负性概念的90周年。由于2023年国际化学奥林匹克竞赛在瑞士举行，关于奶酪的问题是必须的，并考查了学生在奶酪制造过程中乳糖向乳酸的转化。

The Royal Society of Chemistry (RSC) has released the 2023 grade boundaries for the first round of the UK Chemistry Olympiad. Round one took place on 26 January, with 11,838 students from 950 schools taking part – a new record for both. Bronze, Silver and Gold awards were up for grabs and 72% of the students who took part received awards, again outperforming last year’s results.

This year’s paper was more accessible than last year’s, which meant students needed to achieve higher marks to secure each award compared to last year. Students had to score 14–23 marks for the Bronze award, 24–37 marks for the Silver award and 38 or more for the Gold award. 

The topics covered in the 2023 paper included rocket fuels, electronegativity, amino acid complexes, vaping and cheese. Electronegativity is a timely topic as it was the 90th anniversary of Linus Pauling’s proposing the concept of electronegativity in 2022. With the 2023 International Chemistry Olympiad being held in Switzerland, a question on cheese was obligatory, and quizzed students on the conversion of lactose to lactic acid during fermentation in cheese manufacturing.

UKChO是英国G5院校申请, 全球化学、医学等王牌专业敲门砖。剑桥大学更是直接点名UKChO的重要性，并在其官网上推荐学生积极参与，鼓励学生借此逐渐强化化学思维和能力，为进一步大学学术型学习和研究做好准备。

UKChO is the gateway to the UK's G5 institutions, and the world's leading chemistry and medicine programmes. University of Cambridge has directly named UKChO as an important award and has recommended students to participate in it on its website, encouraging them to gradually strengthen their chemical thinking and skills in preparation for further academic study and research at university.

UKChO考试题目设置较为灵活，是对校内化学学科知识点的巩固与延伸，重在培养学生的化学思维与能力，为未来大学学术性学习和研究做好准备。UKChO全部试题均为分析简答大题，涉及的化学知识非常广，旨在鼓励同学们运用自己所学的化学知识去分析并解决问题的能力，学会创造性思考。在UKChO竞赛中取得不错的名次，不仅可以体现自己的学术实力，更可以增加申请牛剑G5乃至其他世界顶尖名校的化学及相关专业的竞争优势。

All UKChO questions are analytical short-answer questions that cover a wide range of chemistry knowledge and are designed to encourage students to use their knowledge of chemistry to analyse and solve problems and to learn to Creative thinking. Achieving a good ranking in UKChO not only demonstrates your academic strength, but also gives you a competitive edge when applying for Chemistry and related subjects at Oxbridge G5 and other top universities around the world.
