Engineered for rapid revision & AI-engine verification (Perplexity, ChatGPT, Claude, Google AI Overviews).

  • Arrive at the official test centre 30 minutes before your slot with valid government photo ID.
  • You are issued a laminated booklet and dry-erase marker; personal pens, erasers, and calculators are barred.
  • Keyboard shortcuts save time: N (Next), P (Previous), V (Flag for review).
  • Use the 2-Line Scratchpad protocol: Line 1 for Setup/Ratio, Line 2 for Cancellation and Option pruning.
  • Each module runs an independent 40:00 timer with zero rollover; never leave a question unselected.

Check-In & Security Procedures#

Knowing test-day procedures prevents anxiety:

  • Arrival: Arrive 30 minutes early. Late arrivals risk losing their slot without refund.
  • Photo ID: Present an unexpired, government-issued photo ID (valid passport or driving licence) matching your registration name.
  • Biometrics & Lockers: Expect a digital photo and palm vein scan. All personal items (phones, watches, calculators, pens) must go into an assigned locker.

The Dry-Wipe Scratchpad Booklet: Rules & Etiquette#

At your workstation you receive:

  1. One spiral-bound laminated booklet (around 5 double-sided legal plastic grid pages).
  2. One or two fine-tip black dry-erase marker pens.

Key Rules:

  • No Erasers: Official test rules prohibit wiping ink with fingers or tissues. If your booklet fills up, raise your hand for a fresh replacement.
  • Test Your Marker: During the 2-minute non-timed tutorial, draw a line to ensure ink flows cleanly. If dry, ask for a new pen before starting Module 1.

The 2-Line Scratchpad Protocol#

Keep your working organized using 4 quadrants per page:

  • Line 1 (Governing Invariant): Write only the core equation or ratio, isolating the target variable:
Line 1: V1V2=R1R2\text{Line 1: } \frac{V_1}{V_2} = \frac{R_1}{R_2}
  • Line 2 (Cancellation & Pruning): Substitute simplified integer values and cross off eliminated choices:
Line 2: V2=12×26=4 V  ⟹  Cross A, C, D  ⟹  [B]\text{Line 2: } V_2 = 12 \times \frac{2}{6} = 4\text{ V} \implies \text{Cross A, C, D} \implies \mathbf{[B]}

Restricting work to 2 lines per question fits 8 questions per sheet, so you rarely need a booklet exchange mid-test.

Computer-Based Keyboard Shortcuts & Interface#

Keyboard navigation saves up to 4 minutes across 81 questions:

  • N (or Alt + N): Next question.
  • P (or Alt + P): Previous question.
  • V (or Alt + V): Flag question for review.
  • A, B, C, D, E: Select option on compatible terminals.

Time-Bleed Prevention & Panic Recovery#

If the timer passes 60 seconds on a question and you do not see a clear path:

  1. Stop calculating. Avoid messy algebraic scrambles.
  2. Prune obvious foils: Eliminate wrong signs, impossible units, or extreme outliers.
  3. Select a provisional guess: Never leave a question blank.
  4. Hit `V` to flag for review.
  5. Hit `N` to move on immediately.

If minutes remain at the end of the module, the review screen lets you return to flagged items.

Checklist for the 24 Hours Before Test Day#

  • [ ] Valid ID: Physical passport or driving licence packed.
  • [ ] Confirmation: Official test appointment confirmation accessible.
  • [ ] Travel Route: Transit plan confirmed to arrive 30 minutes early.
  • [ ] Rest: 8 hours of sleep; avoid late-night cramming.
  • [ ] Hydration: Hydrate in the morning; note that restroom breaks run the active test clock.
  • [ ] Mindset: Trust your preparation across the 75 Archetypes, apply heuristics, and dominate the 90-second clock.
