RCP Revise: institutional authority from the exam body, correct PANE format, quality-assured. Best for exam calibration — if RCP questions feel manageable, you are ready.
PassPa: comprehensive PA matrix coverage with case-based learning and clinical images (CXR, ECG). Built by PAs from candidate experience. Best for systematic coverage — working through PassPa ensures no matrix condition is missed.
Calibration: RCP Revise. Coverage: PassPa. Both lack adaptive features.
