I assume that everyone has their own version of procrastination. In my mind there are better things to do even though I know I have work I push it off to the side since I expect there to be leftover time to complete. My opinion is procrastination is caused by the low reward signals in the brain when you do it early. It may also be a habit by completing the work later your brain may rush with adrenaline, scientist have found that people in high adrenaline environments tend to crave staying there. I assume this is like a drug withdrawal, it is very difficult to break procrastination because you might want to do the work but your body craves the adrenaline rush that comes with doing it in the last dash. In addition you receive much more dopamine from playing any video game than accomplishing a goal this leads you to also say lets wait. If not for the fact that you will be socially ostracized for not coming to school many people wouldn't. self esteem usually doesn't play a huge role. A proven fact is at least half of top ivy league student's brains cut on the energy used while thinking this leads to your brain going on autopilot to solve problems. Any work that needs you to actively think seems unnecessary to your mind thus leading to procrastination.
yeah evolution wants to conserve energy if it does not feel urgent threat. Exams are not an urgent threat according to instinct. Like if someone insults you . You won't procrastinate on beating him.
Exams actually take lot of energy for brain but don't even provide much pleasure at the moment you prepare for them .
So your instinct thinks it's waste of time.
Instinct is like a really really dumb overbearing parent who would blackmail you .
