Source: The Great Interpretation of Dreams (Ibn Sirin)
An exam in a dream indicates a test from God Almighty. If one succeeds in it, it indicates the strength of his faith and patience. If he fails, it indicates his weakness.
Source: Perfuming Humanity in the Expression of Dreams (Al-Nabulsi)
An exam indicates worry and hardship. Succeeding in it is relief and salvation. Failing in it indicates falling into hardship.
Source: Signs in the Science of Expressions (Ibn Shaheen)
An exam is interpreted as worry. Whoever sees himself being examined will be afflicted with worry.
