Example of three rows from the 2023 exam. Work out the fourth.

How it works

Hints cost XP
You may unlock three per problem, in order. The first says where to look, while the last works a step through on ungraded data.
Worked explanations
NACLO’s own solutions give the answer and skip the reasoning. Read the steps a solver takes to get there.
A clock you control
Nothing runs on a timer unless you set one. When it runs out you get a banner but your answers keep working.
