Mistakes Diary

For each subject, create a set of notes called the mistake diary. In here, copy out or cut out and pasted every single question you get wrong throughout the year. Trust me, it fills up fast at the start but as the year goes on you’ll notice that you’re adding less and less to this book.

Why? Because writing down what you got wrong forces you to reflect and review your mistakes, so you won’t be making the same error a second time. This is vital for all subjects, and regardless of whether your mistakes are “real” or “silly” mistakes.
