In this paper, we are discussing the case of offering retired assessment items as practice problems for the purposes of learning in a system called ACT Academy. In contrast to computer-assisted learning platforms, where students consistently focus on small sets of skills they practice till mastery, in our case, students are free to explore the whole subject domain. As a result, they have significantly lower attempt counts per individual skill.
