I reckon 90-93. The rankings are better then they look because the cohort is quite large
First off, raw internal marks are pretty meaningless, but since you claim to have high rankings, I guess it cancels out. Second, I wouldnt give too much weight to your schools estimate, as all estimates are pretty unreliable (especially the ones given by many schools). Everyone here offers an opinion, I dont see how your opinion carries more weight than others, especially considering what you have said in this thread.
