How do you write a good essay in 40 minutes?

The best thing you can do is prioritize that is the key element in any timed event spend 5 minutes or so brain storming then began wrighting like normal include a good eye catching beginning rather that be a question or quote then include 3 middle paragraphs and I the end restate everything that you already said and if you have extra time go back through and change some more common words to bigger words to increase the readers belief in you understanding the topic

1. take a deep breath 
2. think about what you want to write about
(do some quick reseach , if needed)
3. get paper and write down a few key points about the topic
4. take those key points and go into detail (rough draft )

5. DO IT
