Core Course Waivers

I am curious as to what experiences may be with waiving core courses. I understand the trade off, more time getting to know/bonding with your sections vs. the opportunity to take more electives.

I am looking at Ross in particular and I almost feel like I would be able to test out of three or possibly four of the core courses. I doubt that I will attempt to do that many but my thinking is that if I already know this "basic" stuff, why not push myself into the more difficult/interesting courses.

What do you guys think? How often is this done? Am I underestimating what is covered in the core economics, accounting, or statistics courses? Should I simply relax and enjoy some somewhat "easier" classes my first semester to get adjusted?
