The MRCGP has three components: the AKT (applied knowledge), the SCA (simulated consultation assessment), and workplace-based assessment. No single platform covers all three well — and the candidates who try to use one tool for a two-tool job consistently underperform on one component.
SCAreVision specialises in SCA simulation. iatroX specialises in AKT adaptive revision and clinical reference. They are complementary tools for the same qualification. This article explains how they fit together and why using both costs less than most trainees expect.
What SCA Revision Does
SCAreVision is the most established SCA platform in the UK, trusted by over 9,000 GP trainees. Founded by GPs who passed the MRCGP and identified a gap in available resources, it has grown from 90 cases at launch in August 2023 to over 350 cases covering all RCGP clinical experience groups.
Standard membership (£11.99/month, no minimum sign-up): 350+ expert-written SCA practice cases, 350+ AI-simulated patients for solo voice-based consultation practice, 12 detailed consultation guides covering how to structure different consultation types (breaking bad news, chronic disease review, mental health, paediatric, medically unexplained symptoms), a mock exam generator simulating the real 12-case exam format with time pressure, a condition explanation randomiser for practising jargon-free patient explanations, and a group revision mode.
The group revision mode is SCAreVision's most distinctive feature. One person plays the doctor, another plays the patient, and a third observes and marks — all connected via QR code sharing. This replicates the three-person role-play that SCA preparation requires, without everyone needing to be in the same room. SCAreVision strongly recommends against revising for the SCA alone — their platform architecture reflects this by making group practice frictionless.
Premium membership (£15.99/month): Everything in Standard, plus 70+ consultation videos with marking breakdowns. Each video shows a full consultation followed by detailed marking analysis — where the candidate scored well, where marks were lost, and how communication strategies affected each domain. Some videos deliberately showcase weak performances to illustrate common pitfalls. The videos are the closest thing to sitting in on a real SCA without being in the room.
Marking alignment: All cases are marked against the three RCGP SCA domains — Data Gathering and Diagnosis (systematic information gathering, appropriate differential diagnosis), Clinical Management and Medical Complexity (evidence-based management, shared decision-making, safety netting), and Relating to Others (rapport, empathy, patient-centred communication). The marking proforma aligns with the publicly available RCGP reference proforma, so you are practising against the same criteria examiners use.
What SCAreVision does well: SCA-specific consultation simulation at genuine scale. The case bank is the largest dedicated SCA resource available. The cases are clinically authentic — written by GPs who have sat and passed the exam — and cover the breadth of presentations the SCA tests: undifferentiated presentations, chronic disease management, mental health, paediatrics, ENT, dermatology, MSK, women's health, and complex multimorbidity. The group revision feature solves the practical problem of finding study partners when your training peers are scattered across different practices. The consultation videos (Premium) provide the "what does a good consultation actually look like?" reference that many trainees lack — most registrars have never watched a model SCA-standard consultation from start to finish.
What SCAreVision does not do: AKT knowledge preparation. Clinical guideline reference. Clinical calculators. CPD logging. Postgraduate exam coverage. SCAreVision is a single-component, single-exam tool — and that is not a criticism. It is the consequence of deep specialisation. The platform does not know or test the clinical knowledge that underpins your SCA consultations; it tests how you deliver that knowledge in a consultation setting.
What iatroX Does for the MRCGP
iatroX addresses the knowledge and reference side of the MRCGP — and extends well beyond it.
AKT adaptive Q-bank (free). Mapped to the AKT blueprint with adaptive difficulty and spaced repetition. The AKT tests clinical medicine (80%), evidence-based practice (10%), and health informatics/administration (10%). The adaptive engine identifies your weakest clinical domains — if your cardiovascular knowledge is strong but your dermatology is weak, the engine serves more dermatology questions. The performance dashboard shows proficiency across all AKT domains. Free — no subscription, no trial period.
Clinical AI (Ask iatroX). Instant NICE/CKS/BNF answers for verifying management plans. This is directly useful for the SCA — specifically the Clinical Management and Medical Complexity domain. When you are preparing a consultation on heart failure, Ask iatroX confirms the current NICE NG106 stepped care pathway (ACEi/ARB, beta-blocker, MRA, SGLT2i) in seconds. When you need to explain anticoagulation options in AF, Ask iatroX provides the CHA₂DS₂-VASc thresholds and DOAC selection per NICE NG196. Your SCA management plans are only as strong as your clinical knowledge — and iatroX is the fastest way to verify that knowledge is current before you practise delivering it.
Calculators. QRISK3, CHA₂DS₂-VASc, CURB-65, CKD-EPI, PHQ-9, GAD-7 — the exact clinical tools the AKT tests and that inform real consultations. Understanding what the scores mean and when to apply them is tested in both the AKT (directly) and the SCA (through your management decisions).
Guidance Summaries and UKMLA Academy. Condition-specific summaries anchored to NICE guidelines — useful for building the clinical knowledge foundation that makes your SCA consultations clinically authoritative rather than vaguely reasonable.
CPD logging. Creates reflective CPD entries from clinical questions and Q-bank performance — building appraisal evidence throughout your training rather than scrambling before your annual review.
Why They Are Complementary, Not Competing
The SCA tests how you conduct a consultation. The AKT tests what you know. Both matter, and they require fundamentally different types of preparation.
You cannot prepare for the SCA with a Q-bank. The SCA tests real-time consultation skills — your ability to gather information systematically, build rapport, explain management plans in patient-friendly language, negotiate shared decisions, and safety-net appropriately. These are performance skills that require practice with cases, role-play partners, and feedback on your actual consultation delivery.
You cannot prepare for the AKT with role-play cases. The AKT tests applied clinical knowledge under time pressure — 200 questions in 3 hours 10 minutes. It requires rapid retrieval of factual knowledge, interpretation of data (ECGs, blood results, epidemiological studies), and application of current guidelines to clinical scenarios.
Both components require strong clinical knowledge foundations. A candidate who does not know the NICE depression pathway (NG222) will deliver a weak SCA consultation about depression AND answer AKT questions about depression incorrectly. iatroX provides the knowledge layer that underpins performance in both components — the adaptive Q-bank tests and strengthens it, the clinical AI verifies it against current guidelines, and the calculators provide the tools you reference in both exam settings and real practice.
The recommended workflow: Study the clinical topic on iatroX (Guidance Summary for the overview + Ask iatroX for specific guideline questions and edge cases) → practise the consultation on SCAreVision (case-based role-play with marking against the three SCA domains) → lock in the clinical knowledge with iatroX adaptive quiz (spaced repetition ensures it sticks). This three-step workflow — learn, practise, retain — is more effective than either platform used alone because it addresses different cognitive demands in sequence.
What the Clinical Knowledge Gap Looks Like in the SCA
The SCA is not purely a communication exam. Clinical Management and Medical Complexity is one of the three domains — and it specifically tests whether your management plan is evidence-based, comprehensive, and appropriate for the clinical scenario. Candidates who have strong communication skills but weak clinical knowledge consistently lose marks in this domain.
Concrete example: a patient presents with palpitations and is found to have atrial fibrillation. A candidate with strong communication skills but weak clinical knowledge might recommend "starting a blood thinner" and offer to "refer to a cardiologist." A candidate with strong clinical knowledge knows to calculate CHA₂DS₂-VASc (iatroX Calculators provides this), explain that a score of 2 or more in men or 3 or more in women triggers anticoagulation per NICE NG196, discuss DOAC options with their respective advantages, address the patient's bleeding risk using HAS-BLED, and safety-net with clear instructions on when to seek urgent review. The second consultation scores significantly higher in Clinical Management — and the knowledge difference is what iatroX builds.
Another example: a patient presents with low mood. The candidate who vaguely recommends "an antidepressant" scores lower than the candidate who explains NICE NG222 stepped care — active monitoring if mild, SSRI if moderate-severe, the choice between sertraline and fluoxetine, expected onset of action, the need for follow-up at 2 and 4 weeks, and when to consider referral to IAPT. That level of specific clinical knowledge is what separates a pass from a strong pass in the SCA — and it is what the iatroX AKT Q-bank and Ask iatroX build daily.
Common Mistakes in MRCGP Preparation
Mistake 1: Starting SCA practice without building knowledge first. Candidates who jump into SCAreVision cases in week one often practise delivering incorrect or vague management plans. They build fluent consultation habits around wrong content — which is harder to fix than starting from scratch. Build the knowledge on iatroX first (weeks 1-4), then practise delivering it on SCAreVision (weeks 5-12).
Mistake 2: Ignoring the AKT until 3 months before the sitting. The AKT covers an enormous breadth of clinical knowledge — 200 questions spanning every clinical domain. Cramming this in 3 months is stressful and inefficient. Starting iatroX adaptive practice in ST1 — even 10 questions per day — means the spaced repetition system has 12-18 months to build and consolidate your knowledge before the exam.
Mistake 3: Using one platform for both components. No platform does both AKT and SCA well. Passmedicine does not teach consultation skills. SCAreVision does not teach clinical knowledge under time pressure. The temptation to find "the one platform that covers everything" leads to compromise on both components. Accept that MRCGP preparation requires at least two tools — and budget accordingly.
The Full MRCGP Stack
AKT: iatroX (free adaptive Q-bank) + Passmedicine (£35-50 for volume) or Pastest (£95-180 for depth and data interpretation).
SCA: SCAreVision Standard (£11.99/month) or Premium (£15.99/month for video cases). Supplement with SCAPrep (AI-generated cases for variety) or MedTutor AI (AI feedback) if budget allows.
Clinical reference: Ask iatroX (free — NICE/CKS/BNF AI reference).
CPD/Portfolio: FourteenFish + iatroX CPD logging.
Cost Analysis
Combined cost for AKT + SCA: iatroX (free) + SCAreVision Standard (£11.99/month × 3 months = £36) = £36 total. That is less than a single month of many premium medical education subscriptions.
Add Passmedicine (£35/4 months) for AKT volume, and the total rises to £71 — still less than any single comprehensive MRCGP package.
Add SCAreVision Premium (£15.99/month × 3 months = £48) instead, and you get consultation videos with marking breakdowns for £83 total with iatroX + Passmedicine.
When to Start Each
ST1: Start iatroX adaptive AKT practice — even casually, 10-15 questions per day. The spaced repetition means knowledge accumulated in ST1 is retained through to the AKT sitting in ST2-ST3. Use Ask iatroX as your daily clinical reference from day one of training.
ST2 (6 months before AKT): Intensify iatroX AKT practice. Add Passmedicine or Pastest for question volume and data interpretation practice. Aim for 30-40 questions per day.
ST2-ST3 (3-4 months before SCA): Start SCAreVision. Begin by reading cases and consultation guides. Progress to active role-play with study group partners. Use iatroX to verify your management plans before practising them in consultation simulations.
ST3 (final month): AKT mock exams on iatroX + Passmedicine/Pastest. SCA mock exams on SCAreVision mock exam generator. Use the iatroX performance dashboard to identify any remaining AKT weak areas for final targeted drilling.
Verdict
If you are preparing for the SCA, SCAreVision at £11.99/month is the market leader for good reason — 350+ cases, AI patients, group revision, and consultation videos. No other platform matches its SCA-specific depth.
If you are preparing for the AKT, iatroX is the strongest free adaptive option available — with spaced repetition, topic proficiency tracking, and clinical AI reference that extends beyond the exam into daily practice.
Use both. They cost less combined than most trainees expect — and together they cover both MRCGP components more effectively than any single platform attempting to do everything.
