The scores for the pKa and [Acid] answers and Overall Score 1 are expressed as the % correct of the submitted answers, i.e. no penalty was applied for unselected choices. Overall Score 2 assumes that both entries were submitted for each question page, i.e. an estimate of how well you identified pKa and [Acid] for each graph.
