PLAB attempts: how many you get and what if you fail

The GMC’s rules on failed attempts for PLAB 1 and PLAB 2, the fifth and final attempt, and what to do after a fail.

6 minute read · reviewed 24 October 2026

The GMC’s rule is the same for both exams. Checked against the GMC website on 31 October 2026.

SituationWhat the GMC says
You fail PLAB 1You can book the exam again if you still meet all the requirements, until you have failed it four times
You fail PLAB 2The same four-attempt rule applies to PLAB 2
Four failed attempts at either examYou can apply for a fifth and final attempt. It is not automatic
Applying for the final attemptYou cannot apply immediately: you need at least 12 months of additional learning and development after the fourth fail

The GMC says the 12 months is meant for remedial learning and professional development, to give you the best chance in a final, exceptional attempt.

After a fail: a practical plan

  1. Read your feedback: for PLAB 1 the ten area scores, and for PLAB 2 the quantitative and qualitative feedback. See PLAB 1 pass mark and PLAB 2 pass mark.
  2. Plan around the two-year rule if you have already passed PLAB 1.
  3. Budget for the retake: see PLAB exam fees.
  4. Change what you did, not only how much: get feedback from a study partner or a structured course.

For the wider picture, see the published pass rates. They describe all candidates, not your own chance of passing.
