PLABable for MLA and iatroX both offer free access to UKMLA/PLAB question practice. Both have mobile apps on iOS and Android. Both target the same exam. The difference is in the learning model: PLABable is built around community and peer discussion. iatroX is built around AI-adaptive personalisation and clinical reference. Understanding the difference — and where each platform is strongest — helps you build a preparation strategy that draws on the best of both.
PLABable: The Community-Driven UKMLA/PLAB Q-Bank
PLABable for MLA provides 5,000+ questions designed to mimic MLA AKT difficulty. The platform was originally built for PLAB preparation and has transitioned to cover the converging PLAB/UKMLA content, making it relevant for both IMGs sitting PLAB and UK graduates preparing for the UKMLA.
The most distinctive feature is the community layer. Every question has a comments section where candidates discuss reasoning, flag potential errors, share alternative approaches, and debate edge cases. This peer discussion creates a collaborative learning environment — you do not just see whether you got the question right or wrong, you see how dozens of other candidates approached the same question. For difficult or ambiguous questions, the discussion thread often contains more learning value than the official explanation.
WhatsApp study groups organised by exam cohort provide peer support, accountability, and resource sharing. For IMGs preparing in isolation — often in a different country from the exam centre, without access to a study group or tutorial programme — the WhatsApp community provides the social infrastructure that formal education programmes offer to UK-based trainees. This is a genuine differentiator: loneliness and isolation during PLAB preparation are well-documented barriers to candidate wellbeing and performance, and PLABable's community features directly address this.
Revision guides sit alongside the Q-bank, providing structured written content for topic learning. The guides include highlighted key points and are designed as reference material to complement the question practice — read the guide, do the questions, discuss in the comments.
PLABable offers free 1-month full access with a UK university email (.ac.uk) — a strong acquisition hook for UK students. Paid subscriptions apply after the free month or for users without UK university emails. Mobile app on iOS and Android.
What PLABable does well: Community learning at scale. The per-question comments create a collaborative knowledge-building environment that no other PLAB/UKMLA platform replicates. The WhatsApp groups provide social support. 5,000+ questions is a competitive bank size. The free month with .ac.uk email removes the barrier for UK students. The revision guides provide structured learning material alongside the Q-bank.
What PLABable does not do: Adaptive learning — questions are static and do not adjust to your performance. No AI features — no AI tutor, no AI clinical reference, no AI-generated study plans. No spaced repetition algorithm. No topic-level proficiency dashboard showing mastery by MLA content area. No clinical reference for guideline verification during study or clinical practice. No postgraduate exam coverage. The free month with .ac.uk email excludes most IMGs, who typically do not hold UK university email addresses — the very audience the platform was originally built for.
iatroX: The AI-Adaptive Platform
iatroX provides a free UKMLA Q-bank with adaptive difficulty and spaced repetition — no time limit, no university email required, no trial period. Free for everyone, permanently. This is a meaningful access difference: an IMG in Lagos, Dhaka, or Cairo has the same free access as a medical student in London.
The adaptive engine analyses your performance across every MLA Content Map domain after every question and serves the next question to target your weakest area automatically. You do not need to manually select weak topics or configure custom quizzes — the system identifies your gaps and addresses them in real time. Spaced repetition ensures previously-weak topics resurface at intervals optimised for long-term retention.
The topic proficiency dashboard shows mastery by MLA content area — not peer comparison, but absolute proficiency against the exam standard. You can see exactly which clinical presentations and body systems need more work, and the adaptive engine acts on this data continuously without requiring your intervention.
Ask iatroX provides clinical AI grounded in NICE/CKS/BNF/SIGN — taking natural language clinical questions and returning cited, guideline-grounded answers. When a Q-bank question explanation leaves you unsure about the underlying guideline rationale, Ask iatroX lets you explore further: "Why is ramipril first-line here and not amlodipine?" / "What changes if the patient has CKD stage 4?" This builds the clinical reasoning depth that the exam increasingly rewards — and that persists into clinical practice.
The UKMLA Academy provides 402 structured condition pages covering all 18 body systems — each with clinical features, red flags, tiered investigations, NICE-based management, and exam tips. These function as study notes integrated within the platform — no separate resource purchase needed.
Post-UKMLA: the same platform covers MRCP, MRCGP AKT, MSRA, PSA, and 7 postgraduate diploma exams. MHRA-registered. Mobile app on iOS and Android.
Key Differences
Community vs AI. PLABable's strength is peer discussion — the social learning dimension that develops through shared problem-solving and collaborative reasoning on individual questions. iatroX's strength is AI-powered personalisation — the adaptive engine that targets your individual weak areas without requiring peer input. These are genuinely different learning mechanisms, and both have evidence supporting their effectiveness. Social learning builds understanding through discussion and debate. Adaptive targeting builds mastery through optimised individual practice. The best preparation uses both.
Access model. PLABable's free month requires a .ac.uk email — effective for UK students but exclusionary for most IMGs (who are PLABable's historical core audience). After the free month, paid subscriptions apply. iatroX is free for everyone, permanently — no trial period, no institutional email requirement, no credit card. For IMGs in low-income countries, this access difference is meaningful.
Adaptive learning. PLABable is static — every candidate sees questions in the same rotation regardless of performance. iatroX is adaptive — the engine responds to your individual performance in real time. Over an 8-week preparation period, the cumulative effect of adaptive targeting versus static rotation is substantial: the adaptive candidate concentrates hundreds of additional questions on their weakest topics, while the static candidate distributes the same effort evenly across topics they have already mastered and topics they have not.
Clinical reference. PLABable has no clinical AI or guideline reference. When a question explanation is unclear or you want to verify the underlying guideline, you need to open a separate browser tab and search NICE CKS yourself. iatroX's Ask iatroX provides this in seconds within the same platform — and continues to serve this function throughout your UK clinical career.
Post-exam utility. PLABable is an exam tool. After passing PLAB/UKMLA, it serves no further purpose. iatroX transitions into clinical reference, postgraduate exam preparation, and CPD — a career platform, not a single-exam tool.
Who Should Use Which
IMG wanting peer support and community learning → PLABable. The WhatsApp groups and per-question discussions provide the social infrastructure that isolated PLAB preparation lacks. No other platform replicates this community layer at scale.
IMG wanting adaptive, AI-driven preparation → iatroX. The adaptive engine targets your individual weak areas without requiring you to identify them yourself. The clinical AI verifies UK guideline answers in real time.
UK medical student wanting free UKMLA practice → iatroX. Free permanently without institutional email requirement. UKMLA Academy provides integrated study notes. Adaptive engine provides precision targeting for finals.
Budget-constrained IMG without UK university email → iatroX. PLABable's free month requires .ac.uk email; iatroX is free for everyone.
IMG planning a long-term UK career → iatroX. The same platform covers MRCP, MRCGP, MSRA, PSA, and diplomas — no platform switching after PLAB.
The IMG Preparation Reality
Most PLAB/UKMLA preparation guides are written as if candidates have unlimited time, stable internet, and a supportive study environment. The reality for many IMGs is different: preparation happens around full-time clinical work in their home country, often with variable internet connectivity, without access to a formal teaching programme, and without peers preparing for the same exam in the same city. Resources need to work offline (or on mobile data), fit into fragmented study periods, and not assume access to NHS clinical exposure for context.
PLABable addresses the social isolation problem through WhatsApp groups and per-question discussion. When you are the only person in your city preparing for PLAB, the WhatsApp group becomes your study group, your motivation source, and your sanity check. This is not a trivial feature — it addresses a real barrier that affects preparation quality and candidate wellbeing.
iatroX addresses the guideline knowledge problem. Most IMGs have strong clinical knowledge from their medical training — but that knowledge is anchored to their home country's guidelines. The UKMLA tests UK-specific management: NICE pathways, BNF prescribing conventions, NHS referral criteria, 2-week-wait thresholds. An IMG who manages hypertension per JNC 8 (US) or ESC/ESH (European) guidelines will answer NICE NG136-based questions incorrectly — not because they lack clinical knowledge, but because the specific guideline differs. Ask iatroX provides instant verification of UK-specific guidelines, enabling IMGs to systematically learn the UK approach to each condition as they encounter it in Q-bank practice.
Timeline Strategy for IMGs Using Both Platforms
Months 1-3 (foundation building): iatroX UKMLA Academy — work through the 18 body systems systematically, learning the UK-specific management for each condition. Use Ask iatroX to verify any guideline differences from your home-country training. Start adaptive Q-bank practice at 15-20 questions per day.
Months 3-6 (intensive practice): Increase iatroX adaptive practice to 30-40 questions per day. Join PLABable WhatsApp group for your target sitting. Use PLABable per-question discussions to test your reasoning against other candidates — particularly for questions where you are unsure.
Final 4 weeks (exam simulation): Timed mocks on both platforms weekly. Use iatroX performance dashboard to identify remaining weak MLA content areas. Use PLABable revision guides for any topics needing structured re-learning. Concentrate final-week practice on weak areas only — the adaptive engine handles this automatically on iatroX.
The Combination Strategy
PLABable and iatroX complement each other because they serve different learning needs.
Daily adaptive practice: iatroX — 20-30 questions per day with the adaptive engine targeting your weakest MLA content areas. Use the performance dashboard weekly to track proficiency trends.
Community discussion and peer learning: PLABable — when you encounter a difficult or ambiguous question on either platform, check PLABable's comments section for peer discussion. Join the WhatsApp group for your exam cohort for motivation, resource sharing, and accountability.
Guideline verification: Ask iatroX — when any Q-bank explanation (on either platform) raises a "what does the UK guideline actually say?" question, Ask iatroX provides the cited answer.
Study notes: UKMLA Academy (402 conditions) + PLABable revision guides — use whichever format suits your learning style for each topic. Both are available within their respective platforms.
Mock exams: Run timed mocks on both platforms. Compare your performance across the two environments to identify any consistency gaps.
Total cost: As low as £0 (iatroX free + PLABable free trial or .ac.uk access). Even with a paid PLABable subscription, the combined cost is lower than most single-platform alternatives — and the coverage is broader because you are drawing on two complementary learning models rather than one. For context, a single MedRevisions subscription costs $10.80/month; using iatroX plus PLABable free tier gives you adaptive AI plus community learning at zero cost.
Verdict
PLABable for community learning, peer discussion, and the social support that isolated PLAB preparation demands. iatroX for adaptive, AI-driven preparation, guideline-grounded clinical reference, and career-long platform progression.
Neither platform covers PLAB 2 (OSCE) preparation — that requires Geeky Medics, dedicated OSCE courses, or peer practice with clinical skills stations. Both platforms are complementary to OSCE preparation, not substitutes for it.
Both are free to start. Use PLABable's WhatsApp groups for peer support while using iatroX's adaptive engine for personalised revision. The two platforms solve different problems — and the candidates who use both solve more problems than those who use either alone.
