I think the focus in this instance was to actually assess using modality terms (ie. pivotal, crucial, paramount, significant, etc.) rather than in the options section where, for example, the family essay asked you to explicitly use the effectiveness criteria (ie. RAREMAP - thanks paul95!).
Anyway, what's done is done. There's no need to worry now - just focus on acing everything else!
Good luck to all fellow Legal BoS students!
