From August 2024 PLAB 1 content is fully based on the MLA (Medical Licensing Assessment) content map — approximately 430 core conditions organised by clinical presentation. The standard is FY2 level: safely manage common and important clinical presentations as a foundation doctor.
UK and EU centres delivered by VICTVS on behalf of the GMC. International centres include India, Pakistan, Nigeria, Egypt, UAE, Saudi Arabia and others — high-demand cities. Seats often fill within minutes of release.
Variable — set per diet using criterion referencing. Typically settles around 60-65% (approximately 110-116 of 180 items). The pass mark accounts for paper difficulty.
A PLAB 1 pass is valid for 3 years for entry to PLAB 2 (the CPSA / clinical skills component). PLAB 2 is held at the GMC's Manchester assessment centre.
PLAB 1 has sittings in February, May, August and November. Eligible candidates can check available places and book through GMC Online. Use the GMC exam and results calendar for scheduled dates; availability varies by location.
Choose a topic for focused revision and check your plan against the official specification.

Two timed 180-item mock papers under exam conditions weekly. Review every incorrect answer in detail against current authoritative guidance. Pacing practice — finish on time without rushing.
Bookmark review only. Targeted reading on UKMLA-new topics (transgender health, GMC Good Medical Practice 2024, palliative care). Confirm GMC booking and admission documentation. Sleep, hydrate, do not learn new material.

Yes — for IMGs the exam is still booked through the GMC portal as "PLAB". However, since August 2024 the content has been fully UKMLA-aligned (mapped to the MLA content map). The GMC has signalled a gradual administrative transition, but the timing is not confirmed. For practical purposes: book PLAB, prepare using MLA-aligned resources.
PLAB 1 has sittings in February, May, August and November. Eligible candidates can check available places and book through GMC Online. Use the GMC exam and results calendar for scheduled dates; availability varies by location.
180 single-best-answer items in 3 hours (~1 minute per question). Computer-based. UK and EU centres delivered by VICTVS; international centres in major cities. Questions are clinical vignettes testing application of knowledge at FY2 standard.
A PLAB 1 pass is valid for 3 years for entry to PLAB 2 (the CPSA / clinical skills component held in Manchester). If you don't pass PLAB 2 within 3 years you'll need to retake PLAB 1.
You may attempt PLAB 1 up to 4 times. After 4 unsuccessful attempts you must demonstrate 12 months of additional clinical learning to be permitted one final (5th) attempt. Most candidates pass within 1-2 attempts.
The content and standard are the same — both are based on the MLA content map at FY2 level. The administrative pathway differs: UK students take the AKT integrated into medical school finals; IMGs take it via the GMC portal as PLAB 1. The question difficulty and standard are calibrated to be equivalent.
