AP Traumatic-Stress Disorder; Something that most(maybe all) students experience after taking a really difficult AP course when they encounter material related to that AP course.
{In an AP Biology class}
Person A: After taking AP Chemistry, I get traumatic flashbacks to it whenever I hear or see significant figures. I failed the AP Exam because of them.
Person B: Dude, that is some bad AP TSD, except for me, it's whenever someone mentions derivatives
AP Biology Teacher: Don't forget to account for significant figures when calculating the water potential!
Person A: (Hello darkness my old friend...)
