Have you asked if your parents' companies sponsor Students? Some companies like to help students. For example, my dad's company sponsored one of my brother's... However, my brother was outstanding in his studies. By the end of Uni, he was classed 5th in the whole of Europe for his subject whilst being at the top 5 Universities in the world for his subject!
With that said, you should look around at companies sponsoring you. It's also a great way to set up your career because most sponsors work in a way where you work for the company at the same time as you're studying.
Search around for a little. Contact some games companies etc. Usually they sponsor people in their final year of studies, but it's not unheard of to be sponsored throughout your course!
