Hello everyone. I would like to ask regarding the the question bank for mrcs part one .. which one is the best ?? emrcs or pasttest ?? Or do we need to study both??

.

Over the past few months, we've had the privilege of helping doctors prepare for MRCS through our free teaching sessions, YouTube videos, notes, and the MEDICOPLASTY community. One thing has become clear—many candidates don't struggle because they lack ability; they struggle because they don't have a structured study plan. That's why we created the MEDICOPLASTY MRCS Part A Course. This is a structured, exam-focused programme designed to help you study efficiently, build confidence, and maximise your chances of passing. What you'll receive: ✅ Complete MRCS Part A syllabus coverage ✅ High-yield anatomy and basic sciences ✅ SBA & EMQ practice with explanations ✅ Live interactive teaching ✅ Recorded sessions for revision ✅ Mock exams and exam strategies ✅ Ongoing support throughout the course 💷 Course Fee: £250 📅 Course Starts: August 2026 ⚠️ Limited seats available. To maintain small-group teaching and personalised support, places are strictly limited and will be allocated on a first-come, first-served basis. If you'd like to secure your place or have any questions, get in touch today. 📞 Call or WhatsApp: 07453 315868 We look forward to helping you achieve your MRCS Part A success.
