As one of my future classmates pointed out, admits are not be allowed to disclose the actual figures and other information from the portal (I've skipped the agreement first time I logged in, because I wanted to see the portal itself), so I put up some diagrams without any figures.
In R1 and R2 nearly an equal number of people were admitted:
If we compare the actual number of people who confirmed their R1 admission (including those from waitlist) with the number of R2 admits, the diagram will change:
So... let's suppose that the yield of R2 will be, say, 60%... and no one from R1 & R2 defers their admission... and the class size will be 320... then the number of places for R3 & R4 applicants will be as following:
By the way, current female rate is 26%.
UPD: Last year figures in Angie's post.
