Ditto the above. I don't know anyone in our class who had a problem with theirs, but then again, people with bad credit reports may have had their acceptances rescinded....I doubt it's a common occurence thought.
If you think you may have some blemishes on your credit report, it would be a good idea to request a copy of yours and get to work on rectifying it. You also need to check to make sure there aren't mistakes that need to be fixed....apparently this is a common problem. Having a clean credit report is necessary for many aspects of life, not just acceptance to MCW.
