You are not handed a place with SEAS. It allows people who have had difficult circumstances to be compensated. They have to write a few hundred words explaining how their results have been affected. But of course there may be some who are not truly deserving of it, who are "handed" undue and indeed unfair advantage.
However even with this extra consideration, applicants still need to achieve quite high scores relative to the . It isn't a golden ticket whereby one can achieve 60 and get into Med.
Also, your question has sparked a thought.
What is it that one who is naturally gifted at something has done? They have not worked hard, which you have shown is what you believe should be the main determinant in what score is awarded.
Same can be said for SEAS candidates, though I daresay many of them DO work hard, it is assumed that their score is not truly representative of what they could have achieved without the (approved) adverse conditions. So they have not performed to the same level as those who they are given a place instead of.
