 ### Assignments
 These are coding assignments that you will complete, based on neuroscience data. There is an assignment due approximately every second week, except weeks when projects are due. The first assignment is mandatory for everyone, and it's important because it will teach you how to access course materials and use the tools required for the rest of the course. All of the other assignments are mandatory, however --- if and only if you submit *all* of the assignments --- the grade on the assignment you did worst on will be dropped (see table below).
