Having written the flashcards, I'd say they cover the majority of the Core Reading. Because of the style of the flashcards (quick fire Q&A), you can't cover the Core Reading word for word. The flashcards are designed to be used alongise the Core Reading or alongside the ActEd Course Notes rather than as a substitute. A useful exercise would be to anotate the flashcards, create a few of your own as you go through the course.
