Check the legend, permitted links and distance definition before choosing.
Review original grid questions on distance, direction, nearest points and coordinates, without real navigation or dispatcher qualification.
Read only this module’s units and conditions. Untouched work, missing answers and unattempted modules remain explicit. No overall, percentile, pass estimate or hiring level.
A schematic declares its own geometry
- The exercise uses a fictional five-by-five grid. Columns A through E run west to east, and rows 1 through 5 run north to south. Every allowed horizontal or vertical link counts as one segment and can be travelled in both directions. Diagonal movement is excluded. These conventions make the small questions checkable. They do not describe an actual town, the physical length of a street or the conditions under which a vehicle could travel.
- Two connections are closed: B2–B3 and C4–D4. A closed link removes that particular connection without removing or renaming either endpoint. The visual diagram and its written description express the same information. Use whichever format helps you inspect the facts. The six questions cover several operations on that one diagram; they are not a calibrated spatial-ability test or a complete simulation of dispatch map work.
A route follows allowed edges
- For a shortest-route question, count permitted segments rather than drawing a straight line between endpoints. A route cannot cross either closure or use a diagonal shortcut. Moving to a neighbouring column or row normally adds one segment, but a closed connection may require going around through another row or column. The shortest distance is the smallest number of allowed segments among valid routes, not the first route that happens to catch your eye.
- Several routes may share the same minimum length. A distance question can therefore have one correct count without there being one uniquely correct route. The original answer key checks the count against the declared graph. This distinction matters when reviewing a response: a different route is not automatically wrong if it respects every connection and has the same minimum length. Actual travel time and real-world routing require information this equal-length exercise does not supply.
Direction, proximity and coordinates ask different questions
- A direction question asks where one point lies relative to another under the legend. Moving from row 4 toward row 2 in the same column means moving north because row 1 is the northern edge. A coordinate question combines a column letter and row number to identify one node. Neither question requires choosing a shortest route. Read the requested operation before applying a method that was useful for a different question.
- Nearest in this module means the fewest permitted segments from the named starting point. It does not mean the shortest straight-line distance or the quickest journey in traffic. Compare each offered destination using that same rule and account for the closures. A point that looks close on the page could require a detour. The original nearest-point question is constructed to have one best count among its alternatives, without an unresolved first-place tie.
A closed edge does not erase its endpoints
- Imagine a different fictional square with points A1, B1, A2 and B2, where A1–A2 is closed and the other three edges are open. Getting from A1 to A2 then takes three permitted segments through B1 and B2. A2 remains south of A1 under a north-at-row 1 legend, despite the detour. The route length and the relative position are two distinct facts about the same small diagram.
- Use the example to check which fact a question requests before choosing an option. It does not show that a person who answers quickly has a better sense of direction or is suitable for navigation work. Familiarity with coordinate labels, diagram conventions and the particular bank can affect the exercise. The page does not observe the strategy you used, the route you considered or the source of a mistaken count.
Read the six answers and their conditions
- The result keeps correct, wrong and unanswered counts separately, adding to six. An unanswered item is not replaced with a selected wrong option, and an entirely unanswered completed section can still be reviewed. Each explanation identifies the relevant graph fact or operation. There is no map-reading type, norm percentile, professional level or pass prediction, and these counts are not averaged with the other modules’ different units.
- The timed mode uses a site-defined three-minute cap; untimed study has no performance clock. Selections are checked against the active deadline before they are accepted. Expiration closes the section and preserves untouched items as unanswered. Backgrounding, leaving or inconsistent clocks clear the active timed section rather than inventing a comparable interval. Those are recording conditions for the original exercise, not evidence of an official assessment’s timing or standards.
Inspect a tiny invented graph
- For optional practice, draw a small fictional grid and mark one closed edge. Write the permitted neighbours of each point, then compare two routes between the same endpoints by counting edges. Ask a willing partner to check the connections and whether a shorter route exists. You can also describe the graph in words and solve from that description. This makes the declared relationships inspectable without claiming to train a general spatial faculty.
- Do not use the fictional diagram for a real journey, an operational route or an emergency response. No road conditions, traffic rules, vehicle constraints, access rights or live closures are represented. For actual work, rely on the authorized current information and applicable procedures. If those sources disagree, the appropriate next action may be clarification rather than improvising from a simplified practice rule. Keep real location information and private work details outside this page.
A diagram count is not a qualification
- The grid, questions and readings are original FermatMind material. They do not reproduce official CritiCall maps, items or scoring, and no vendor evidence validates this particular bank. It has no established hiring validity, norms or English–Chinese performance equivalence. The same coordinate codes appear across both interfaces, while wording is bilingual. That design does not prove equal task conditions for people using different languages, devices or accessibility tools.
- All six complete readings are public before any exercise and stay open when every module is unattempted. You may finish by understanding one distinction between position and route length, or simply read without taking the section. No personal location, retained answer profile or paid report is required. A public link contains the general title and entry only; it does not contain your map answers, a route history or a statement about your suitability for a job.
