ENAC Running Comparison
IntellectualPSY1A stream of simple calculations, one at a time. For each one, tick whether its result is identical to or different from the one it's compared with: the result just before, the one two back, or a fixed value X, depending on the block. The exam format is 100 answers in four blocks of 25, about 12 minutes.
Overview
The sums are easy. Holding on to the results is the test. Keep the last results going round in your head: two of them under C, one under B. When a new result comes, compare it with the oldest one in your loop, tick, then swap that oldest one for the new result. On a match the swap changes nothing, so your loop never gets out of step. Say it under your breath at first, then silently once it runs by itself. The trap is the change of condition: after a block of C it's easy to keep comparing two back. Read the condition screen and reset your loop before the first calculation. If you lose the thread, leave an answer or two blank while you pick it up again, because a wrong tick costs a point and a blank costs nothing. Two calculations later your loop is full again. And watch the sign: 35 and −35 aren't the same.
Assessments
Part of the Air France Cadets selection at ENAC (PSY1) battery as “Mémoire de travail II”.
A hundred simple calculations to answer in four runs of twenty-five, each one on screen only long enough to be worked out. For each one you say whether its result is the same as the one you are comparing against, and what you compare against changes three times during the test: the result two calculations back, then the one just before, then a fixed value, then two back again, though the first three can come in another order. This one subtracts points for a wrong answer, and the working-memory test that runs beside it does not.
Battery mappings are based on public information and may change.
Three conditions
- Condition C: is the result the same as the one two calculations back? The block’s first two calculations get no question.
- Condition B: is it the same as the one just before? The first calculation gets no question.
- Condition A: is it equal to X? X is 50, and the condition screen shows it.
- The same result counts, whatever the numbers: 65 + 10 and 35 + 40 are both 75, so that’s Identical.
- In the exam, a calculation stays up for 2 seconds, then there’s a 1.5-second blank, then the boxes come up for 3 seconds. A click ticks a box and a second click unticks it.
Nine answers under C, B and A
There’s no clock here. Each calculation waits for Next, and each answer is corrected before the next one.
Game Phases
Know the Three Conditions
C is two back, B is one back, A is X = 50. The condition screen gives you the letter, and X under A, nothing more.
Work It Out While It's Up
The calculation goes after 2 seconds. Have the result before it does.
Compare, Tick, Swap
Compare the new result with the oldest one you're holding, tick, then put the new one in its place.
Untick Before You Switch
Ticking the second box doesn't clear the first, and two ticks count as wrong. So untick first.

10 exercisesENAC M2-back numérique
Digits come up one at a time, a new one every 3 seconds. From the third one on, you say for each digit whether it's the same as the one 2 before it. The exam format is 62 digits, 60 of them with a question.
ENAC M2-back couleurs
Coloured squares come up one at a time. From the third on, say whether each one is the same colour as the one two before it. The exam format is 42 colours, 40 answers, in 2:06.
ENAC Memory N-Back
Letters come up one at a time, and for each one you say whether it’s the same letter as the one three, four or five before it. Capitals and small letters count as the same. The exam format is two tests back to back: a 3-back then a 4-back for ENAC EPL, a 4-back then a 5-back for Air France Cadets. It hasn’t been set since 2020.
Visual N-Back
Shapes in colours go past one at a time. On every one, say whether it is the same shape AND the same colour as the one a few places back — and the lag you are matching against changes from block to block.
Associative Memory
Memorise a set of symbol–number pairs, then after a short delay recall which number went with each symbol.
Acoustic Memory Test
Hear a spoken sequence once, hold it through a filled delay, and type it back — exactly in order.
Parameter Memory Test
Aviation parameters flash up on a dark display, then vanish. Reproduce the data row by row, from memory, before the clock runs out.
Grid Challenge
A dot memory test in the format of gridChallenge, Aon's official name for its working memory module: dots flash one by one on a scattered field, quick yes or no puzzles interrupt between flashes, then you click the dots back in order.
ENAC Memory Calculation
You get a calculation, then a letter, then another calculation and another letter, and so on. At the end of the board, you type the letters back in the order they came. The exam format is 20 boards, from 3 letters up to 9, with 5 seconds a calculation and 1 second a letter.
ENAC Reversed Series
Digits come up one at a time in the same spot, a second each. When they’ve gone, you type them back in reverse, the last one first. The sequences grow from 4 to 9 digits. The exam format is 12 sequences, about 3:30.
