What it is

An ordering puzzle gives you a few people or things and clues that compare them: taller than, sits to the left of, lives above, comes before. You build the full order from the clues, then answer questions about it.

The exam uses four kinds:

  • Ranking: age, height, score, years of service.
  • Seating in a row: left, right, next to, between.
  • Floors: above, below, directly above.
  • Time order: before, after, first, last.

All four are solved the same way: draw a line, place the sure things first, and never place anything the clues do not force.

Why it matters on the exam

Ordering sets appear in the logic part of the Professional exam, usually as a short puzzle with two to four questions. One correct diagram answers every question in the set, and one wrong placement can cost you the whole set.

The same skill helps at work: ranking applicants, scheduling tasks in order, or assigning offices to floors.

Rule 1 of 5Diagram the comparisons (linear ordering)
Draw one line and decide which end means "more". Write the first person named in the middle, place each person as you read the clues, then check every clue and answer from the finished diagram.
Worked example 1 of 4Ranking: years of service
Five clerks are ranked by years of service; no two have the same. Abe has served longer than Bea. Cris has served less than Bea. Dante has served longer than Abe. Ella has served less than Cris. Who has the second shortest service?
  1. Abe
  2. Bea
  3. Cris
  4. Ella
Step 1 · Set the lineLeft = longest service, right = shortest. Start with Abe in the middle.
