Key points
- PLAB 1 is a <strong>180-question</strong> SBA paper completed in <strong>3 hours</strong>—book via <strong>GMC Online</strong> only.
- You cannot “swap” dates: you typically <strong>cancel first</strong>, then re-book any alternative place you’re eligible for.
- The <strong>42-day rule</strong> matters: cancellations <strong>42 days or less</strong> can cost <strong>100%</strong> of the fee.
- If you’re seeing rumours about “agents”, bots, or paid booking services: treat it as a <strong>risk to your account and future registration</strong>.

Step 2 — Use the PLAB booking service to compare locations and dates
Step 3 — Confirm what “changing dates” actually means
Step 4 — Treat cancellations like a financial decision
Step 5 — Build your ‘exam day admin’ checklist

Do this well before you want to sit the exam. You want to be ready the moment you’re eligible to book, rather than losing weeks to admin delays.

Return to this sectionIn practice, you typically cancel your existing booking if you want an alternative slot, then book another place you’re eligible for. Read the booking guidance carefully before you click—this is where candidates make expensive mistakes.
Return to this sectionThe amount you lose depends on how close you are to the exam date. If you’re anywhere near the 42-day threshold, pause and check the fee table before acting.
Return to this sectionKeep your booking confirmation and centre details to hand, plan travel conservatively, and remove preventable failure modes (wrong centre, wrong ID, late arrival, or last-minute cancellations).
