01 / Get familiar
What you’ll practise.
This practice asks you to learn a priority rule from a visual reference and apply it to changing dial arrangements. The pointer on each dial identifies the colour used to decide its checking priority.
Check white first, black second and grey third. When more than one dial has the same colour priority, use alphabetical order of their labels. Each question is marked on the complete checking sequence.
Rule Learning

02 / The format
How the practice works.
Study Reference

Answer Questions
Each question shows a different diagram with the same rules
Set the checking order
Use the mock’s ordering controls to arrange the dials in priority order, including any alphabetical ties.

03 / Your approach
A few things to try.
Study the Reference Carefully
The reference phase has no time limit. Take your time to thoroughly understand the rules before starting questions.
Learn the System Completely
Memorize the priority or checking rules from the reference. The same rules apply to every question—you just need to apply them correctly.
Use the Reference Panel
Use the reference available in your chosen mock to check the colour-priority and alphabetical tie-breaking rules.
Precision Matters
Most questions require the EXACT correct order for full credit. Double-check your ordering before submitting each answer.
04 / Before you begin
Common questions.
What is the TRP2 test?
TRP2 stands for Trainability for Rules and Procedures Part 2. It tests your ability to learn a checking system from a reference diagram and apply it to order dials by priority. Each dial has colored segments (white, black, gray) with a red triangle pointer indicating which color to check first.
How does the checking order work?
The red triangle pointer on each dial points to one of three colored segments. White = Check 1st (highest priority), Black = Check 2nd (medium), Gray = Check 3rd (lowest). You order all dials based on what their pointer indicates.
What is the tiebreaker rule?
When multiple dials point to the same color, use alphabetical order of their letter labels. For example: if dial A and dial B both point to white, A comes before B. This is crucial for getting the exact order right.
How long does the test take?
The core practice starts with a self-paced reference phase. The additional practice pack uses an eight-minute question timer. Read the instructions for your chosen mock before starting.
Can I see the reference diagram during questions?
Core practice includes a collapsible reference panel during questions. Read the chosen mock’s instructions for the reference available during its question phase. The checking rules use colour priority and alphabetical tie breaking.
How is scoring calculated?
All-or-nothing scoring: each question requires the EXACT correct order. Partial credit is not awarded for getting some dials in the right position. Your final score is the percentage of questions answered correctly.
Can I practise for free?
Core practice is free and can be used without an account. Sign in if you want completed results saved to your account. The optional additional practice pack is a separate purchase.
