Thank you for using the timer!
We noticed you are actually not timing your practice. Click the START button first next time you use the timer.
There are many benefits to timing your practice, including:
Yea, you've got the right idea, assuming it says 80% score within X to Y. I've always assumed they did this fairly - 80% around the mean, but I suppose the above poster is right, they could play some statitstics games here and give you the bottom 80%... though I doubt thats how they do it.
If you are within the 80% range, you may get in, but you'll have to have some strong supporting pieces to your application. For instance, if your GPA is weak, I wouldn't even consider applying with something in the bottom end of the range (unless youve taken courses since undergrad and achieved A's).
Geez it was early and I rushed that, so my answer sucked Rhyme. I expect it is 10-90% they give. I doubt it would be 20-100%.
What I was meaning to say was that it could be that the 90%-100% range is all sat on 620. You don't have a sufficient data set to know the shape of the tail (normal distribution would seem fair, but this is no less likely).
Whatever, you are in the wrong tail (the low end) so need to give good reasons why to be accepted.
