Advanced Glass Tempering (GANA) The GANA exam presents a proctored, computer-based assessment spanning 150 minutes with 80 multiple-choice questions weighted toward scenario-based problem-solving. You’ll navigate real-world tempering challenges—evaluating stress distribution, diagnosing furnace failures, and optimizing cooling cycles. The structure deliberately mixes straightforward recall with applied reasoning, forcing candidates to connect thermal physics principles to production-floor decisions rather than simply naming equipment components.
