DD needs to start revising. Except she doesn't know where to start, or how much she should be doing.
She has to revise in Welsh so resources are limited, and school aren't very helpful. She's not top set so will have to try hard.
What are the best ways of revising and how much per day. She has a dance class most nights but can revise between. The month before exams she'll drop them temporarily.
Any help would be appreciated.
