Mixed practice covers selected anatomy and basic-science lessons, not the complete bank or a balanced mock paper. Patient labs include separate decision questions and reassessment.
Expand topics with +; collapse with −. All existing lessons remain available. Independent exam preparation—not an official MRCS resource or a substitute for supervised clinical practice.
