ENAC Slid Shapes
IntellectualPSY0Two 6 × 6 grids and a tray of pieces. Slide pieces onto your grid until it matches the figure beside it. A light cell of a piece flips the square under it and a dark cell changes nothing, so two light cells on one square cancel out. The exam format is 5 boards with 3 minutes each.
Overview
Every square that has to change ends up under an odd number of light cells, and every other square under none or two. So read the two grids before you look at the pieces, and keep the dark cells out of your head: they only take up room. Then start where the choice is smallest. A square to change in a corner or along an edge often fits one piece only, and the biggest piece fits in the fewest places. On the later boards you'll have to stack, flipping a square with one piece and back with another, so a grid that looks wrong halfway through can still be on the way. If nothing comes together after a minute, clear the grid and start from a different piece.
Assessments
Part of the Air France Cadets selection at ENAC (PSY0) battery as “Formes glissées”.
Two grids and a tray of pieces: slide the pieces onto your grid until it matches the figure beside it. Sliding only: a piece is never turned over or turned round. A light cell of a piece flips the square under it and a dark one leaves it alone, so two light cells on one square cancel out, the order you place the pieces in changes nothing, and not every piece in the tray has to be used. Five boards, and they get harder as they go.

Two grids and a tray of pieces
- The figure on the left is what your grid has to look like. Your grid starts different.
- A piece slides onto your grid as it is. It never turns. You can stack pieces, and move a placed piece as often as you like.
- A light cell of a piece flips the square under it, light to dark or dark to light. A dark cell changes nothing. So two light cells on one square cancel out, and the order you place pieces in never matters.
- The board is done the moment your grid matches the figure, even with pieces left in the tray.
Nine squares to change
Nine squares differ between your grid and the figure. Three pieces, and all three are needed.
Game Phases
Find What Changes
Compare your grid with the figure before you look at the pieces. Only the squares that differ need a light cell over them.
Start at the Edges
A square to change in a corner or along an edge often fits one piece only. Place that one first, then the biggest piece.
Count on Cancelling
Two light cells on one square cancel. A piece can flip a square that another piece flips back, so don't judge a half-built grid too early.
Clear and Restart
If you're stuck, clear the grid and start from another piece. A wrong first piece costs more than a slow one.

Multitasking & Planning
8 exercisesMultitasking Test
Two tasks at once: scan number grids for duplicate pairs while answering spoken questions from your phonebook, agenda, mental math and word categories — some of which must be answered at an exact moment on the clock.
Planning Test
Build a weekly schedule that satisfies every constraint. Pick a scenario, fill the grid with role assignments, and meet every staffing rule before the timer runs out.
Triple Multitasking Test
Verify chained equations, spot duplicate icons, and keep your aircraft in the gap as hazard lines fall. Three tasks, one screen, one five-minute clock.
Motion Challenge
A ball maze planning test in the style of Aon's motionChallenge: slide the blocks clear and steer the orange ball into the black hole in as few moves as you can. Six minutes on the clock, as many puzzles as you can solve, one level up after every solve.
M-TASK Multitasking Test
Three tasks at once in the Schuhfried M-TASK format: work a symbol queue in its stated priority order, fill arithmetic blanks against a time bar, and reorder symbol rows to match a target. One clock, a neglected panel drags the whole score, and every run records a replay. Or go endless in Challenge, where the first mistake ends the run.
Task Manager
Enter new autopilot values quickly and accurately while cancelling red alerts within three seconds — the COMPASS-style two-task screen, on one shared keyboard.
ENAC Marble Tubes
Two boards of three tubes hold the same numbered marbles. Count the fewest moves that turn the top board into the bottom one, then click that number. A move takes the top marble of a tube and puts it on top of another tube. The tubes hold 3, 2 and 3 marbles. The exam format is 10 boards with 20 seconds each.
ENAC Airspace Conflict Watch
Aircraft cross two bands of six airways, blue ones from right to left and violet ones from left to right. Each band has a grey zone that can never hold more than 4 aircraft, or more than 2 blue ones. You close airways to keep both zones within their limits, and you divert as few aircraft as you can. The exam format is 10 boards in a row.
