Your biggest screwup? (Academically)

<p>My analog watch stopped working during my Electromagnetics midterm. The exam had 3 problems and I thought I had more time to answer the last one then I did. Had 1/3 of the exam graded 0 (not to mention not getting full credit on the other 2/3) and decided to drop for fear of not being able to ace the final exam.</p>
