Distance learning can offer a solution to a long-standing challenge of undergraduate education: how to assign an appropriate amount of work to each student, and how to assess this work efficiently. In this paper I describe the Depository of Repetitive Internet-based probLems and Lessons (DRILL), an online system for providing education and assessment for precalculus, which can substitute for routine problems given in homework and as exam questions. Its special features include:
- adaptive testing,
- on-the-fly question generation,
- instant assessment,
- context-sensitive help,
- question balancing, and
- two-dimensional test design.
