摘要： Methods, computer program products, and systems are presented. The methods include, for instance: obtaining an unmarked questionnaire form and creating form metrics data of the unmarked questionnaire form, receiving a selection marked form having freehand marks and determining selections data by quantifying a center point of a freehand mark and by comparing the center point with the form metrics data. Selections data may be adjusted according to positional consistency amongst the freehand marks if one mark is ambiguous as to the distances to answer choices.
