Gasboys is a completely free, non-profit web site dedicated to making it less onerous for anaesthesia trainees (Gasboys and Gasgirls, anaesthesia registrars and anesthesiology residents and fellows) to pass their Fellowship examinations and, hopefully, become better anaesthetists, or even anesthesiologists. The site contains a growing collection of over 6000 anaesthesia related multiple-choice questions, covering physiology, pharmacology, physics, statistics, and the latest clinical evidence. You are very welcome to create a free account and begin answering questions. Gasboys aims to have something here for you whether you have been anaesthetising people for four days or four decades. Come back often. The more you do the more you will learn. If you find gasboys.net worthwhile, then please enter discussions, help editing and creating questions and pass the word.
