(A bit of revision for you. Stickystudy relies on the idea of colours. Each time you answer a sticky correctly it changes gradually from lowly “red” to the lofty heights of “green”. Once a sticky is answered correctly four times it becomes green and is never asked again. Also, the more you answer a sticky correctly, the further into the future you are asked the next time - just to make sure you haven’t forgotten. Revision over. Well done.)
