get a full scholarship

Hi! I am an international sophomore student in Financial Economics and International Studies at a good but waay to expenisve college in the U.S. The financial pressure on my parents is becoming unbearable. I need out, and I would love to get full tuition covered at another college. That would be sweet.
So. I am trying to keep my grades up, and starting the application process and thinking up kickass essays. And I will need really strong ECs too. Wish me luck!!
