In preparation for your final essay here's a link to a forum where the steps are presented in a clear way. There's also a list of topics you can practice. Practice makes perfect, so keep writing. An example of the rubric for the evaluation is also available here for you to be familiar with it.
I wish you all the best in your finals. Should you have any questions about any of the topics in the course, please feel free to post your questions and I'll reply with resources for you to prepare.
I found this video and I said to myself "you have to share it with the guys". It made me think of the times when things don't go as planned... try to keep this example in mind and remember life is about not giving up!
