I think that “Chicago is too much work, I want to transfer to an easier school” is not going to impress the admissions staff at any highly ranked rigorous university. Duke is a highly ranked rigorous university.
Also, I am not sure that I understand from your posts (I did look at two previous ones) what you want in a university. You don’t want to transfer and then discover that you are no happier than you were at Chicago.
“Graded on a brutal curve” is what you get in highly ranked schools. The thing about Duke or Chicago (or MIT, Stanford, Caltech, or any Ivy League school) is that nearly everyone there was in the top 10% of their high school class, and most were significantly higher than this. There are smart people everywhere at both Chicago and Duke. That is part of the fun, but is also much of what makes these schools so demanding. There is an old saying that if you are the #1 top student in your high school, then you might be average at a “top 10” university.
You have only been a few weeks at Chicago. It is a step up from high school. It is even a step up from a highly ranked private high school. A’s will take a lot more work than they did in high school.
I am not sure what RSO is (I thought it was a cannabis oil product). However, research opportunities will come along. This takes some time.
In terms of meeting people, this takes time also. You should participate in some clubs and activities. You will meet people like you over time. At a top school like Chicago, people who are “like you” are going to be more common than they were in high school. However, it will still take time to find them.
If you were accepted to Chicago, that means that the admissions staff at Chicago feel that you can handle the work. However, you are going to need to work very hard to do so. It will pay off big time to (i) show up at every class; (ii) sit near the front; (iii) always pay attention; (iv) keep a good record of what work you need to get done; (v) keep ahead in your homework at all times; (vi) seek out help early if you need it; and (vii) treat everyone with respect whether they deserve it or not. Many, many students sort of cruise through an easy four years in high school, get to a rigorous university (such as Chicago or Duke), and sort of hit a wall. Suddenly they have to learn quickly how to study.
One last thing, my recollection is that Chicago is on the quarter system. This makes it even more important to stay ahead in your homework. Personally I loved the quarter system, but it takes a bit of getting used to.
