I had 2 friends fail the exam. They were in the top 15% of our class. This is the bottom line to not failing...... Other than your normal routine steps you should already know when interviewing and examining (wash hands, drape, etc..).....YOU MUST memorize each case in the back of the step2 CS book. They include all the typical disease processes...pnemonia, depression, chest pain, cough, fatigue, etc. For every illness the First Aid will list from "A to Z" ALL the questions you must ask and ALL the physical exam maneuvers you need to do. The people you are interviewing/examinating usually have no medical background, but they have the same checklist that is listed in the back of the first aid. Both students memorized those cases and passed on the 2nd attempt.
