Of K3M and IChO Selection

Recently, I realised the flaws of K3M as a benchmark for the preliminary selection of IChO candidates. This is because K3M consists of 40 MCQs only. The usage of MCQs as a screening test is very unreliable. This is because it is not very sensitive and neither is it specific in identifying students who are really good in Chemistry. A set of more extensive and structured questions are in my opinion more sensitive and specific for that purpose. However, I do not have the statistics to prove my arguments and all of this is merely based on personal experience. I do hope that the IChO selection and training committee will look into this problem and come out with a better solution.
