Users who have purchased premium question packs will have a period of 1 month (30 days) from the announcement date to contact us at [email protected] to receive a digital copy of the purchased questions (e.g., in PDF format). The prerequisite for sending such materials will be successful verification of the proof of purchase (e.g., the GPA transaction number from Google Play).
