<p>I wanted to edit but waited for too long, here is the full explanation.</p>
<p>My case is fairly special. I spent time in Europe before going to my current school. As a result I have a lot of credits but I consider that I don’t have the classes I need to go on. My status is a junior but I want to do applied math and it is inaccessible in my school.
My current US GPA is 3.47 and 3.62 in math. I mostly got As in math but one B when I took a really heavy workload.
Considering that I am an international without financial aid, it makes me fairly interesting for school and I am interested in a very specific area of mathematics: Modeling and statistics in biology. As a result, Michigan and HMC are very appealing to me.</p>
<p>However, Carnegie and Chicago offer majors in operative research which covers my interests but not exactly related to what I want to do.
Moreover, at least for Carnegie, I will need to retake the TOEFL. I e-mailed Chicago about it and hope to get a response after the week end.
I would need to improve my overall TOEFL scores and especially my speaking skills that was low when I passed the test 2 years ago.
One of my problem with that is that I have already been in the US for a while with a decent GPA and that schools that appeals more to me don’t need it. This is why, I wonder if I want to apply to Carnegie and Chicago</p>
