The incumbent vs the insurgent.
SCA Revision has been serving GP trainees since the CSA era (2013). The platform offers 350+ expert-written cases with mark-scheme breakdowns, 70+ consultation videos with examiner-perspective marking, group revision via QR code, and AI patients via SCARevision.ai. 9,000+ users. From £11.99/month.
SCA Prep launched more recently with an AI-native architecture: unlimited case generation with domain customisation and PDF export, an AI tutor trained on UK clinical guidelines, AI patient roleplays with RCGP-based marking, and a WhatsApp revision tutor. From £14.95/month.
What Each Does Best
SCA Revision's advantages: Volume of human-curated content (350+ cases), consultation videos with marking commentary (unique to this platform), group revision feature, and the longest track record in the market. The written cases with mark-scheme breakdowns are the gold standard for understanding what examiners look for.
SCA Prep's advantages: Unlimited case generation (you never run out), an AI guideline tutor for clinical questions, WhatsApp delivery for passive revision, and the fastest content iteration (already covering August 2025 curriculum update). The AI-native architecture means the platform gets better as the underlying models improve.
The Trade-Off
SCA Revision's content is human-curated — every case was written by a GP trainer who passed the exam. The quality is proven. SCA Prep's content is AI-generated with human oversight — the volume is unlimited but the clinical nuance may be thinner.
Both now offer AI patients — SCA Revision via SCARevision.ai (ElevenLabs/Deepgram/ChatGPT), SCA Prep natively. Neither platform's AI patients are yet as convincing as professional simulated patients (Emedica), but both provide useful solo practice.
Where iatroX Fits
Both platforms test SCA readiness. iatroX ensures the knowledge underpinning your consultations is solid — adaptive revision, guideline-grounded explanations, and clinical calculators for the quantitative cases.
