 The Medics branch of the University's rag organisation, Karnival, is one of the most successful, and organises events such as the Bed Push, a yearly event in late October where students dress in scrubs and white coats and push hospital beds from the QMC into Old Market Square in Nottingham city centre, stopping motorists and pedestrians on the way and collecting money for charity.The University of Nottingham at Derby (UNAD) runs events and sports for students based at Derby, and there is also a regular "hopper bus" between the two sites.There are numerous medical school societies, including sports clubs, music and drama groups, and academic organisations such as SCRUBS Surgical Society.
