<p>According to the Penn admission website "A total of 5,756 international students applied for admission to Penn's undergraduate schools for Fall 2012 and 438 (eight percent) received admissions offers"</p>
<p>Considering 17.7 percent are from Canada and Mexico for which admission is need blind
Penn:</a> Penn Facts</p>
<p>So they consider these as international students, but don't consider aid in the admission process. Obviously, I can't get the number of applicants from those places to eliminate them from the calculations, so I think I will just apply the overall admission rate of 12.43% giving me (438 * 0.177) / 0.1243 =~624</p>
<p>Leaving us with a total of 5132 applicants for about 360 places.</p>
<p>Now to the aid part</p>
<p>"Please note you will be in competition for very limited funds. In recent years, we have offered an average of 45 aid awards
to admitted freshmen, and one or two to admitted international transfer students."</p>
<p>I read somewhere else that is was about 60 for the 2016 class, but I can't seem to find that anymore, so I'll have to use 45 as the figure.</p>
<p>Now, I obviously can't finish the calculations because I don't know the ratio of students applying with aid and those applying without.</p>
<p>So I will just be calculating it for every 10% (students applying for aid)</p>
<p>10%: 6.82% - 8.77%
20%: 7.67% - 4.38%
30%: 8.77% - 2.92%
40%: 10.2% - 2.19%
50%: 12.3% - 1.75%
60%: 15.3% - 1.46%
70%: 20.5% - 1.25%
80%: 30.7% - 1.10%
90%: 61.4% - 0.97%</p>
<p>On the left are the odds for applicants without aid, on the right those with aid.</p>
<p>Obviously, I can't actually use this without the information about the applicants and my calculations were very crude, but if someone did know the approximate percentage of students applying requiring aid, that would be interesting to know.</p>
<p>Interestingly, at a 50:50 split, the admission rate for non-aid applicants is around that of the domestic rate.</p>
<p>Although, according to user Ceebrown, about 90% of international Penn applicants applied for aid. ;)

<p>Before people have a go at me for calculating this, I just like doing things like this if I have 20 minutes of free time, and Penn admissions is on my mind a lot at the moment. I do realise that this is useless without the other information.</p>
