After enough all-nighters, you learn what works and what doesn’t. Here’s the ranking.

S tier: Instant noodles. Cheap, fast, and shared between eight people with one kettle. Nothing beats them.

A tier: Cold pizza at 4am. It’s technically a crime, but it works.

B tier: Crisps. They’re fine for an hour, and then your keyboard is covered in dust.

Avoid: Anything that needs a fork, anything messy, and anything you can’t eat with one hand.

Drink water, too. Nobody does, and everyone regrets it.
