The transition from PLAB to UKMLA is the most significant change to the IMG registration pathway in a decade. If you are an international medical graduate planning to work in the UK, understanding what actually changed — and which preparation platforms have adapted — determines both your exam performance and your career trajectory.
What Actually Changed
The exam content has converged. PLAB 1 is now aligned to the 2026 MLA Content Map — the same blueprint that UK medical students follow. The 180 SBA questions test applied clinical knowledge mapped to 212 clinical presentations across 18 body systems, with emphasis on NHS-specific management pathways, 2-week-wait referral criteria, and UK prescribing conventions.
The name persists but the substance has shifted. For the 2026 sitting, IMGs still sit "PLAB 1" — but the content is functionally UKMLA-aligned. The 2026 framework explicitly describes its condition lists as indicative and non-exhaustive, meaning the exam can test any condition within the MLA scope, not just a fixed PLAB syllabus.
Greater emphasis on clinical reasoning. The exam has shifted from factual recall toward first-principles clinical reasoning — synthesising history, examination findings, and investigations to reach a management decision. This favours adaptive Q-bank practice (which trains reasoning) over rote memorisation (which trains recall).
PLAB 1 fees for 2026: £283. PLAB 2 fees: £1,036. These are significant costs for IMGs — making free preparation resources particularly valuable.
What the Transition Means for Your Preparation
The PLAB-to-UKMLA convergence has three practical implications for how you prepare.
First, the question style has evolved. Old PLAB questions often tested factual recall — "What is the most common cause of X?" / "What investigation confirms Y?" The new MLA-aligned questions test clinical reasoning — "A 45-year-old man presents with [history]. Examination reveals [findings]. Investigations show [results]. What is the most appropriate next step?" The shift from recall to reasoning means that rote memorisation of facts is less valuable than practising applied clinical scenarios. Adaptive Q-banks (which train reasoning through clinical vignettes) are more aligned with the current exam format than flashcard-based memorisation.
Second, UK-specific content is now central. The MLA Content Map explicitly tests NHS-specific management pathways: NICE guideline-based treatment algorithms, 2-week-wait referral criteria, NHS screening programmes, UK prescribing conventions (BNF-standard drug names, not international generic names), and NHS escalation pathways. IMGs whose training was based on ACC/AHA (US), ESC (European), or other national guidelines will find that their clinical knowledge is often correct in principle but wrong in UK-specific detail. The first-line antihypertensive for a 55-year-old differs between NICE NG136 and JNC 8. The cervical screening programme ages differ between UK and US protocols. These differences are directly tested — and they are the reason UK guideline integration in your Q-bank matters.
Third, the condition list is non-exhaustive. The 2026 framework explicitly states that its condition lists are indicative, not exhaustive. This means the exam can test any condition within the MLA scope — you cannot "learn the syllabus" by memorising a fixed condition list. You need broad clinical knowledge across all body systems, with the flexibility to reason through unfamiliar presentations using first principles. Adaptive Q-bank practice develops exactly this skill — by constantly presenting novel scenarios at the edge of your knowledge.
The Three Platforms
MedRevisions
MedRevisions is the most established PLAB/UKMLA platform — running since 2019 with 30,000+ users. It provides 5,400+ questions mapped to the 2026 MLA Content Map, an AI Professor tutor (analyses weak areas, generates bespoke study plans, turns clinical cases into anatomy/physiology lessons), a Study Essential Mode with approximately 1,800 curated high-yield questions for candidates with 3 months or less, a Readiness Score predicting exam preparedness based on your performance data, 30+ customisable mock exams with a Weakness Mock generator that builds mocks from your worst-performing areas, and integrated Smart Notes with Common Confusions boxes and Differential Diagnosis tables.
Pricing: From $10.80/month (USD). Multiple plans by duration.
Strengths: Largest dedicated PLAB/UKMLA bank. AI Professor is contextual and performance-aware. Study Essential Mode is specifically designed for time-pressed candidates. Readiness Score provides data-driven exam-day confidence.
Limitations: PLAB/UKMLA only — no postgraduate exam coverage, no clinical reference, no clinical AI, no CPD tools. After passing, the platform serves no further purpose.
PLABable for MLA
PLABable provides 5,000+ questions with a community-driven learning model — per-question comments for candidate discussion, WhatsApp study groups for exam cohorts, and revision guides alongside the Q-bank. Free 1-month full access with a UK university email (.ac.uk). Mobile app on iOS and Android.
Strengths: Community learning. Peer discussion on each question. WhatsApp groups for motivation and accountability. 5,000+ questions.
Limitations: No AI features. No adaptive learning. No spaced repetition. No clinical reference. The free month with .ac.uk email excludes most IMGs (who do not have UK university emails). No postgraduate progression.
iatroX
iatroX provides a free UKMLA Q-bank with adaptive learning engine and built-in spaced repetition — no subscription, no trial period, no university email required. Free for everyone, permanently.
The UKMLA Academy provides 402 structured condition pages covering all 18 body systems — functioning as study notes with clinical features, red flags, tiered investigations, NICE-based management, and exam tips. Ask iatroX provides clinical AI grounded in NICE/CKS/BNF/SIGN — particularly valuable for IMGs learning UK-specific management pathways that their international training did not cover. iatroX Calculators provides 80+ UK-contextualised clinical tools.
Post-UKMLA: the same platform covers MRCP, MRCGP AKT, MSRA, PSA, and 7 postgraduate diploma exams. MHRA-registered. Mobile app (iOS + Android).
Strengths: Free. Adaptive AI engine. UK guideline integration. Career-long platform progression. Study notes (Academy).
Limitations: Smaller question bank than MedRevisions (5,400+) and PLABable (5,000+). No Readiness Score equivalent. No AI Professor-style tutor.

Strategy by Timeline
12+ months before exam
Start with iatroX (free) for adaptive practice and UK guideline familiarisation. Use the UKMLA Academy for structured condition learning — work through one body system per week. Use Ask iatroX to verify management pathways against UK guidelines (essential for IMGs whose training used different national guidelines). Build the habit of daily adaptive practice.
6 months before exam
Primary Q-bank: Choose MedRevisions (volume + AI Professor + Readiness Score, from $10.80/month) or iatroX (free + adaptive). Or both — they do not overlap enough to make either redundant. Supplementary: PLABable for community discussion and WhatsApp peer support. Clinical reference: Ask iatroX for instant guideline verification when reviewing wrong answers. Mock exams: Both MedRevisions (30+ customisable mocks) and iatroX (configurable timed sessions).
3 months or less
MedRevisions Study Essential Mode — 1,800 curated questions specifically designed for tight timelines. This is the most efficient path through the essential content when time is short — it strips away low-yield topics and concentrates on the highest-weighted MLA content areas. Supplement with iatroX spaced repetition mode for weak areas identified by the performance dashboard. Mock exams on both platforms weekly — the timed conditions matter as much as the content. MedRevisions Readiness Score as an exam-day decision guide — if the score suggests you are not ready, deferring is cheaper than failing (£283 per PLAB 1 attempt).
Final 2 weeks
Mixed-topic adaptive practice only — no new content learning. iatroX spaced repetition resurfaces previously-weak topics at optimal intervals. MedRevisions Weakness Mocks concentrate on your worst-performing AoCPs. Review the MLA Content Map one final time to confirm no major body system has been missed entirely. Verify your management knowledge for the 20 most commonly tested conditions using Ask iatroX. Rest the day before the exam — fatigue impairs clinical reasoning more than any last-minute revision can improve it.
Beyond the Exam: Why Platform Choice Matters
This is the strategic question that most IMGs do not consider during PLAB preparation — but it has meaningful long-term implications for your UK career.
MedRevisions and PLABable are exam tools. After passing PLAB/UKMLA, they serve no further purpose. You will need a new platform for MRCP Part 1 (if pursuing medical specialties), a new platform for MRCGP AKT (if pursuing general practice), a new clinical reference tool for your NHS posts, a new CPD system for revalidation, and new Q-banks for any postgraduate diplomas. Each transition means a new subscription, a new learning curve, and a fresh start with no performance history.
iatroX eliminates this ecosystem reset. The same platform — same account, same performance data, same clinical reference tools — covers MRCP, MRCGP AKT, MSRA, PSA, and 7 postgraduate diploma exams. Your weak-area tracking from PLAB preparation carries forward into specialty training. Your Ask iatroX habits from exam study continue seamlessly into clinical practice as your daily guideline reference. Your calculator usage from exam preparation becomes your clinical workflow.
For IMGs planning a long-term UK career — not just passing a single exam — starting on a platform that grows with you saves cumulative cost, eliminates platform-switching friction, and builds clinical reference habits that compound over years. The IMG who uses iatroX for PLAB, then MRCP, then daily clinical practice has a continuous, personalised knowledge profile spanning their entire UK career. The IMG who uses MedRevisions for PLAB, then Passmedicine for MRCP, then GPnotebook for clinical reference has three disconnected tools with three separate knowledge profiles and three learning curves.
The IMG-Specific Challenges
PLAB/UKMLA preparation for IMGs involves challenges that UK medical students do not face — and the best preparation platforms acknowledge and address these.
Guideline translation. Your clinical knowledge may be excellent — but it is anchored to your home country's guidelines. NICE recommends different first-line treatments, different investigation thresholds, and different referral pathways compared to US, European, South Asian, or Middle Eastern guidelines. Every management question on the exam tests the UK approach. Ask iatroX provides instant verification of UK-specific guidelines — enabling systematic relearning of management pathways in the UK context. Every time you get a Q-bank question wrong because your management followed the wrong guideline, Ask iatroX shows you the correct UK approach with the specific NICE reference.
Social isolation. Many IMGs prepare alone — often in a different country from the exam centre, without access to a study group, tutorial programme, or peer community. PLABable's WhatsApp groups and per-question discussion partially address this. But the isolation is real, and its impact on wellbeing and motivation should not be underestimated. If you are preparing alone: join the PLABable community (free), set a daily study routine, and use the iatroX performance dashboard to track progress objectively rather than relying on subjective feelings about readiness.
Financial pressure. PLAB 1 (£283) + PLAB 2 (£1,036) + GMC registration + visa fees + relocation costs — the total financial investment to start practising in the UK is substantial. Exam failure means not just repeating the preparation, but paying the exam fee again. Free preparation resources (iatroX) reduce the financial risk. Paid resources (MedRevisions) add value when budget allows — but the marginal benefit of a paid platform over a free adaptive platform should be weighed against the opportunity cost of that spending for an IMG managing multiple large expenses simultaneously.
PLAB 2 (OSCE) preparation. Neither MedRevisions, PLABable, nor iatroX covers PLAB 2. The OSCE requires clinical skills practice, communication training, and physical examination technique — a fundamentally different preparation category. Geeky Medics, peer practice with clinical skills stations, and dedicated OSCE preparation courses serve this need. Plan and budget for PLAB 2 preparation separately from PLAB 1.
Visa and Practical Considerations
GMC registration pathway. PLAB 1 pass is required for GMC registration via the PLAB route. After full UKMLA implementation, IMGs will sit the UKMLA directly. Both serve the same function — demonstrating that you meet the threshold for safe practice in the UK. The GMC route finder tool (available on the GMC website) helps determine which registration pathway applies to your specific qualifications and experience.
Health and Care Worker Visa. Most IMG doctors apply for the Health and Care Worker Visa — a subcategory of the Skilled Worker Visa with reduced fees, no Immigration Health Surcharge, and faster processing. You need a Certificate of Sponsorship from an NHS employer, evidence of English language proficiency (IELTS 7.5 overall or OET Grade B), and to meet the salary threshold (with exemptions for NHS roles on the shortage occupation list). The visa leads to Indefinite Leave to Remain after 5 years.
Clinical attachments. 4-12 weeks of supervised NHS placement. Not formally required for GMC registration, but strongly recommended for specialty training applications — they provide UK references and demonstrate familiarity with NHS systems. Ask iatroX is particularly useful during clinical attachments for verifying UK management pathways in real time — replacing the "I think this is how it's done in the UK" uncertainty with cited guideline answers.
English language requirements. IELTS Academic (minimum 7.0 in each component, 7.5 overall) or OET (minimum Grade B in each component). These must be met before GMC registration, not before PLAB. Some candidates sit PLAB before completing language requirements — this is permitted but delays registration. Plan language testing early in your preparation timeline.
Verdict
No single platform is optimal for every IMG. The best approach combines:
iatroX (free) for daily adaptive practice, UK guideline reference, and career-long platform progression.
MedRevisions (from $10.80/month) for volume, AI Professor, Readiness Score, and Study Essential Mode when budget allows.
PLABable (free to start) for community learning, WhatsApp groups, and peer discussion.
Total cost: As low as £0 (iatroX only) to approximately $10.80/month (MedRevisions) + £0 (iatroX). Both approaches are viable — the key is starting early and practising adaptively. The candidates who pass first time are overwhelmingly those who began preparation months before the sitting, used adaptive tools that targeted their specific weak areas, and verified their management knowledge against UK guidelines throughout.
