<p>If it is only for an exchange, I would choose Cal Poly. I live in California for the moment, but I am British. I had a chance to travel around various states. Given your goal is not to earn a degree from your exchange university I would pick the one with the nicest environment/climate, friendliest people, and very strong academics reputation.</p>
<p>I have visited both Cal Poly and U of I, Cal Poly definitely has the better location and climate. But be forewarned that both schools are located in an isolated location and you need access to a car to go anywhere.</p>
<p>I prefer Cal Poly because it is located in California’s wine country region, off the Pacific coast. It is about 10 minutes from two beautiful beaches, Pismo and Availa beach (Pismo you can actually drive you car along the beach). The atmosphere is classic surfing California culture. Also, there is a nice town in San Luis Obispo with good variety of cuisines and shops. </p>
<p>The climate is very mild, sunny and warm (almost year round) with green rolling hills and small mountains on campus. The central campus is compact but the rest of the school is HUGE with vast of open space (it sort of a giant ranch). So there are lots of outdoor activities on campus like hiking, bicycling, and running. The campus itself is very nice, with lots of very nice buildings and facilities, especially for engineering. </p>
<p>Cal Poly is well known for its engineering and architecture colleges (I think it was something like #2 public undergraduate engineering school w/o phd, and #4 architecture school in the US), so you will have a very solid scholastic experience while there. Given CP is very hands on, you will have many laboratory classes along with lectures. The academic atmosphere there is quite serious, and students do take their studies seriously. Also, the engineering facilities are very nice since they just constructed an engineering building complex not long ago.</p>
<p>As for people, the student body is very relaxed and friendly, but decidedly more monochrome when it comes to races (mostly whites). But on a whole, it is a very welcoming atmosphere. There is a strong sense of student body school pride, so you see lots of pupils wearing Cal Poly clothing.</p>
<p>As for U of I, I agree with the previous post, it is a very good engineering school, one of the best in the US (on par with UC Berkeley, and CMU). If you want to pick the school with the better academics and nothing else, choose U of I. It will be a great learning experience given the caliber of the faculty and the engineering students. </p>
<p>But personally, when I visited (perhaps it is the season and the weather), it was a bit depressing because it felt to be a very isolated environment (the areas outside U of I are just endless corn fields) with a seemingly endless gray sky. It was just too rural for me. In the state of Illinois, it felt like there is nothing outside the city of Chicago. </p>
<p>But this could be just me, but I believe there is some truth to the American idea that all the states in the center of the US are consider “fly-over” states. I.e. you just fly from 1 coast of the US to the other with no need of visiting.</p>
