What's the best way to learn case studies?

Firstly, before learning any case study you must ensure that you understand the content properly as this will make it much easier to learn. Consult different resources such as the internet and textbooks in order to further your understanding or to fill any gaps in your knowledge. Once you've understood all the content of the case study you should then condense your notes into a few key points, the place name, some figures, key events, primary and secondry effects etc. Repeating these few key facts and events, either writing them out again and again or saying them aloud will help with memorising them. Getting a friend or family member to then test your memory of the case study is a good way to determine what you don't know about the case study, and allow you to see what you may need to spend more time learning.
