And it doesnt just work for English either

Ive used an English essay exam question as an example, but your teen could use this technique for all word based subjects. It probably wouldnt be applicable to math or other pure number subjects.
For example, Chris is using it to study for his med school exams. He wont be writing out essays, but he is using questions like flash cards to prompt short answers. Im planning on using this technique a lot during my upcoming exam study, and I hope your teen makes good use of it too.
