The University of Georgia has been using computer-based testing for almost two decades: in part, to expand the formats and types of questions, but also to manage the logistics of administering 1750 first-semester general chemistry hour exams per testing cycle. A proctored computer lab, complete with secure software or a lock-down browser, is quite effective as an alternative to late night exams, although other logistics have their challenges. (Think about how many workstations, exam sessions, and question pools one might need to accommodate the numbers of students.) Starting with JExam,1 software created in-house and then populated with thousands of
questions in a myriad of formats over many years, the general chemistry program recently switched to a commercial, browserbased system hosted by the electronic homework vendor
WebAssign.2 The latter allows programming scripts (in PERL), arrays of data, and other features that provide breadth and novelty essentially limited only by the imagination and skills of
the question writers and programmers.
