Self-Explanation of Worked Solutions

Take a worked solution or a model answer and explain each step out loud, or in the margin: why this step, why now, and how it connects to something you already know. When you cannot say why a line follows, you have found a gap that silent reading would have hidden. It suits subjects where marks come from method and reasoning, such as math, physics, chemistry and economics. The same review that ranked practice testing and spacing at the top placed self-explanation one tier below, as promising, so use it alongside past papers, not instead of them. A good test is explaining a mark-scheme answer to a friend or family member who has not studied the topic; if they follow it, you understand it.
