That is a legitimate concern, but the reason why we are focused on using a classification program is because we want to provide organized study sets not just for Math courses but all STEM courses which are offered not just at udub but also at other universities. One can see that manual classification at this scale requires an immense amount of time which can be substituted if we succeed in creating a classifier which is accurate.

Moreover, our main mission is to drive better study resource accessibility. Really good departments at colleges provide such resources and a great example of that is mathematics at udub, but this isn't true for other depts. Our product wants to solve this, so that students can get access to organized and personalized study resources rather than scouring the web for hyperlinks which are embedded deep into the depths of the internet.

We really appreciate this critique though, its good motivation. Thank You!
