# 4 Review

Review is an important step for retaining the ‘big picture’. 80% of detail is forgotten within 24 hours – so it’s important to review a book, study notes, lecture slides or other materials quickly to help you embed the information.

## How to review

Skim over the information quickly – you don’t need to spend much time. Ten minutes on day 2; five minutes on day 7; two to four minutes on day 30. This will help the information to stay fresh in your mind, so you won’t have a huge mountain of revision to climb later.

Review is an excellent return on investment. A few minutes can potentially save you hours of time when you come to the exams (Knight, 2016).
