It teaches a 4-step method: letters, numbers, endings and check. Along the way you get worked examples with the key words marked, before-and-after fixes that show why the first version loses marks, a one-page visual summary, a quick check to test yourself and a recap of the rules to remember. Each card holds one idea, so you can read it on a phone between practice sessions.
