How to Pass Calculus

I, as a now experienced college student, would like to pass on a helpful hint to those of you looking to pass your calculus classes.
The Dilemma: The last big calculus exam before the final is quickly approaching, and you, although prepared, are feeling the pressure.
The Solution: A simple locked door. You cannot take an exam without somewhere to take it, can you? No.
In reality, no one was conniving enough to have done this on purpose, but as I walked to class today, in anticipation of the big exam, I found a group waiting outside the door of the classroom. Since the professor didn't have a key, there were no open, vacant rooms nearby, and too much time was already wasted attempting to track down someone with a key, we were given the exam to complete at home. A take home exam, you say? Indeed. How can I possibly do poorly? I cannot.
