Questions about this exam policy.
Short editorial answers about how to read the policy and model-specific verdicts.
Q.01Can I rely on this page instead of the official policy?
No. This page is an independent editorial summary. Use it to orient yourself, then confirm current rules with the testing organization before exam day.
Q.02Why are only a few calculators shown right now?
This page shows calculator verdicts that have already been matched to the official policy source and reviewed against the model data. More models can be added after the same review.
Q.03What should I do if my model is not listed?
Use the report issue page to request coverage and include the exact model printed on the calculator body, not only the retail listing name.
