Geometric knowledge and skills are necessary prerequisite for successful engineering study in many branches. Unfortunately, acquiring those is difficult for many even since the very beginning in primary and secondary schools and it needs to be supported.
It is obvious that different students need different amounts of time to solve the same task. We raised a question whether or not the speed at which a student solves different tasks is a characteristic property of the individual student.
We have analysed the data obtained during the eight years of operating GeoTest - an online system for the assignment of construction geometry tasks and automatic evaluation of the correctness of their solutions.
