How can I improve my essays in order to get the top band of marks, my feedback says need more analysis and explanation?

In order to move to the top band of marks, it is important to not just describe and explain, but to give your own point of view on the issue. Giving your judgement is the key to getting the top marks. After explaining, summarise and give your view of causation and effects. Lastly try to be original but back your views up with hard facts.
