Scope of Test compared to ICHO

The purpose of the USNCO is to select those students who have the chemistry skills necessary to compete in IChOs in general as determined by past IChO. In contrast, the testing administered at the actual training camp aims to select those students who have the skills do to well on the topics that will be covered in the immediate upcoming IChO. Since the host country each year may design the test to their preference, the scope of the USNCO and the training camp may be widely different.
