I definitely used to procrastinate just to make school more interesting. It's an adrenaline rush to see if you can finish the project in one night or learn all 50 vocabulary words in the class right before the test. It definitely helps with boredom.
Bingo. This is
precisely why my DD (and her... well, whatever he is... friend who is EG) does this.
Her level of 'full throttle' is kind of legendary at her school. It kind of makes me queasy to think about it too hard, but she ENJOYED catching up 3.5 weeks of APUSH in a few days. It was the thrill of going all-out and still earning 100%, see.
Now that she's caught up, her attention wanders and she isn't so concerned about racking 100% on every assignment. It's a weird, weird phenomenon.
