1. Move closer to your campus
Try to get a room near your campus, it will significantly help to reduce your transportation costs. If you mull over taking a car, then find someone who has the same schedule as you and shares your expenses on parking and gas. But walking, using a bike, skateboard or roller-skates will be cheaper and healthier if you live close to your school.
1. Organize group calls with Google Hangouts
You likely use Skype and FaceTime for audio and video calls quite often. But if you and your classmates have already grown accustomed to using Google Docs, then Google Hangouts, which is integrated into it, will be more beneficial for your team.
