To overcome this limitation, we have developed a grading workflow based on the pairwise similarity score of two considered chemical structures. Specifically, a strict comparison of candidate and expected chemical structures is not sufficient when some tolerance is deemed acceptable. This is particularly true in the case of chemical structures, where most questions simply cannot be evaluated on a true/false basis. Therefore, such platforms are unevenly adapted to different disciplines. Typically, existing online platforms use a binary grading system, which often fails to give a nuanced evaluation of the answers given by the students. We report a novel approach for grading chemical structure drawings for remote teaching, integrated into the Moodle platform.
