We want these lessons to be as widely helpful as possible. Given the range of circumstances in which medical students may find themselves right now, we do not have a single approach in mind. For those with the time, we suggest you proceed through the modules start-to-finish. However, for those with more urgent needs, the modules are stand-alone, and you can selectively access content on an as-needed basis. The subsequent learning objectives and table of contents at the left may help you locate content that is most important.
