Everyone knows that college/university tuition is absurdly high in the US (as well as many other countries). If I were to give one piece of advice to current and future college students, it would be to take advantage of all the free opportunities you can find.
Most schools have a sizable budget they set aside for school events for students, such as social events and speaker talks. Since they often span a large variety of topics, there are bound to be a few that interest each student. In addition, some of them also offer free food!
So, as a student myself at Northwestern University, I decided to make NU Free Food, an automatically generated listing of events around campus that offer free food. If you're a student at Northwestern University, you won't have to go hungry ever again!
