The Cost of Sleep
Determining when to give up and take get some rest is an important thing to learn before finals week. It basically shows the simplistic nature of opportunity costs. One could stay up all night studying and preparing for an exam tomorrow or call it a night. Going to sleep can be beneficial because a well rested person is able to recall and process information faster than someone who is falling asleep during the exam. If a person chooses to stay up and cover more material they might be know a little bit more but they might not be able to actually put the new material to use. One can go to bed earlier and therefore wake up earlier and be able to review the formulas needed right before the exam, so the formulas and equations are fresh in their mind.
