DD 15 finished school last Friday and I've been trying to encourage her to start revision as she has about 7 mocks in January. She's done nothing so far and says I should lay off asking her, she'll start when she's ready. previous revision attempts have been hard work in recent months, sometimes very ask minute. I know it's Xmas but We've got visitors for nearly the whole holidays and I would love her to get started. any advice on how to motivate her or shall I leave her to it?
