What is the best way to do well on a short answer test?

My APWH teacher is notoriously known for having the hardest tests out of anyone at my school. On Thursday, I will be taking her semester final. There is a 40 question multiple choice section, and a 20 short answer section. Most questions are pretty vague because it’s a 800 year AP World History class. <br><br>Ex: “Discuss the differences between the Mongols and the Qing.”<br><br>“The black death affected Europe and Asia in what ways?”<br><br>AM I JUST SUPPOSED TO SPILL EVERYTHING I KNOW ABOUT A TOPIC ON THE PAPER?
