If you did decently well in undergrad and didn't get in due to your special minority status or family connection, I say just really enjoy your long last summer vacation because you won't get one for a very long time. While other dental students may get a good break here and there, you at BU won't and will be stuck in APEX the first two years. Then comes the boards in the next two years and then working hard after graduation to pay off those massive loans. If you got nothing else planned and will be in the city anyway, then go ahead and take it. I recalled some people just didn't have what it take and still flunked out after taking the course and then retaking the final twice.
