Co-op?

<p>I hear several ppl mentioning "Co-op" program. Can anyone explain what this is?
I also heard you can reduce your tuition from $30,000 to $15,000. What process do you need to go over in order to do this?
Besides, does the pharm.D program at NEU have financial aid or Co-op program?(Is fin.aid available for international students?)
I would really appreciate your replies.</p>
