PCO topographical test practice for London private hire applicants

Practise the skill rather than memorising answers

Route planning is transferable. If you learn to scan the road network, check direction and restrictions, and choose a coherent corridor, you can handle an unfamiliar start and finish. Memorising one answer line is much less useful when the map or journey changes.

PCO Topography keeps the accepted route hidden until submission. The live Laravel version does not publish premium model JSON in the web root; the server scores the plotted points against the private accepted model and returns feedback afterwards.

40 full routes and 68 focused drills

The bank contains 108 interactive exercises. Forty are genuine full START-to-FINISH routes. Sixty-eight are focused drills derived to practise shorter decisions, junctions and route features. They are deliberately labelled separately so a short subsection is not presented as a full route.

Use drills to improve a weak skill, then use full routes to test whether you recognise the same issue while managing a longer journey.

What to check before the first click

• START and FINISH
• Broad direction of travel
• Likely main-road corridor
• One-way direction
• Named road closures
• Bridges, tunnels and roads above or below
• The first two junction decisions

This short scan prevents the most expensive kind of mistake: choosing a poor corridor early and then trying to repair it with several later turns.

Use the Practice Score as feedback, not an official mark

PCO Topography measures route choice, direction, position, junction behaviour and endpoint accuracy. The resulting Practice Score is an independent training metric. It is not an official TfL score, pass mark or guarantee of an assessment result.

Start with the free Cassland Road route

Route 010 — London Lane to Gascoyne Road with Cassland Road closed — is the single free submitted practice. It demonstrates the same plotting and server-side feedback flow used by Pro. Once that attempt is submitted, Retry, Next and the rest of the bank require Pro access.

Common mistakes when working on PCO-style topographical preparation

A common mistake is trying to solve PCO-style topographical preparation too quickly. Candidates can recognise the general area yet miss the first important restriction or connection. Slow the decision down long enough to explain why the first road choice works. That small pause is usually cheaper than repairing several later turns after the route has already moved away from the best corridor.

Another mistake is treating every visible difference from the accepted line as the same problem. With PCO-style topographical preparation, the useful question is whether the road sequence is wrong or the drawing is merely imprecise. PCO Topography separates those signals so you can prioritise building route-planning skill rather than memorising alleged question lists. A route-choice correction should come before cosmetic line placement.

Finally, avoid memorising the shape of one map. Repeat the underlying decision on a different exercise. If you can explain the rule and apply it elsewhere, the skill is becoming transferable. That is why the route bank combines focused practice with full routes rather than asking you to repeat one screenshot until it looks familiar.

A practical study drill for PCO-style topographical preparation

Use a three-pass drill. On pass one, inspect the map without plotting and say the likely corridor aloud or write it down. On pass two, plot and submit normally. On pass three, review the first meaningful divergence from the accepted model and state the reason for it in one sentence. This keeps the session focused on decisions instead of random repetition.

For the next attempt, change only the behaviour that caused the main error. If the issue was direction, check arrows earlier. If it was a structure, verify the actual connection. If it was road position, keep the same route choice and place the line more carefully. This controlled correction makes score changes easier to interpret.

Finish by transferring the skill into interactive London route work. Do not require a perfect score before progressing; require that you can identify what you did, why it was correct or incorrect, and what you would check on an unfamiliar map. That is a stronger preparation habit than simply accumulating completed route numbers.

• Scan before clicking
• Choose the corridor
• Check direction and restrictions
• Plot meaningful junction points
• Submit without revealing the answer
• Review the first major divergence
• Repeat the same skill on a different route
