We realized that concentration requirements and course prerequisites are not easily visualized by any of apps at Brown. We wanted something that will allow us to see our progress in our concentration and see what is available to take or what I need to take in order to take some specific class. We really like that we can see the big picture of a concentration and see how courses are interconnected. It's also cool to compare and contrast different concentrations on these factors.
We also access Banner, which is the Brown website that handles student information, in order to retrieve the courses that a student has already taken and then generate a graph of classes colored based on whether they satisfy prereqs, have already taken, or are unable to take.
The typical target user is any student.
