Sixty-three interactions actively involve the learner in the training. Lesson interactions provide the learner opportunities to apply what he or she has learned. The computer assesses the learner's level of understanding of all learning objectives. All questions in this course are fully narrated. Narrations enhance comprehension and are welcome support for learners with reading skill deficits and when English is the learner's second language. When the learner answers a question incorrectly the computer provides remedial instruction and reviews the material until the learner can answer correctly. Mastery's exclusive Follow-up Review, standard in all Mastery Advantage courses, provides time-delayed reinforcement and review of the learner's newly acquired knowledge. The Follow-up Review enhances the transfer of newly acquired knowledge to the learner's long-term memory.

The Learner navigates through the course and its resources using the standard Mastery Control Bar. Course resources include a fully narrated glossary of terms.

The learner can ask for all course information on any topic at any time during the lesson presentations. The learner can use the topical index as a reference source even after completing the course. Closed Captioning is included. A complete transcript of all audio and video files is also provided with this course. Use the transcript file in conjunction with MODIFY to simplify customizations.
