Zeshan Qureshi is a Paediatrician based at Great Ormond Street and the Institute of Child Health. He graduated with distinction from the university of Southampton, and has published and presented research work extensively and internationally in the fields of pharmacology and medical education. Whilst working in Edinburgh he was part of the leadership team developing a near peer teaching programme, where by junior doctors, throughout south east scotland, were both trained to teach, and delivered teaching across every hospital in the area. This book is an extension of this philosophy: that junior doctors and fresh graduates know how to express complex ideas in order for it to be easily understood from a students perspective. That junior doctors can teach, and write in a complimentary way to senior doctors: one that is friendly and fun, easy to read and relevant to both exams, and the day to day to life of junior doctors.
