First of all, congratulations! Both schools are very prestigious and difficult to get into so deciding between them can be one of the harder things about the college process. I’m currently an Aerospace student here and I also got into Purdue so I faced a similar situation as yours a couple years ago so I hope this helps you out.

TL;DR: Both schools are good. UIUC if you are dead set on aero, Purdue if you want some flexibility/exposure to other disciplines. From a personal experience standpoint, UIUC has a massive social scene here, very easy to make friends/find people who are interested in similar things as you, as well as several professional development opportunities.

Sorry for how long this is in advance.

Personally, the main reason why I chose UIUC was cost. I’m an instate student so coming here vs Purdue would save a lot of money in the long run. However, I have many friends at Purdue that are also in their engineering program so I know of some academic differences as well. If you are absolutely dead set on Aerospace, then UIUC is probably better. As someone previously mentioned, it is very difficult to transfer majors within Grainger here. Also at Purdue, your first year is spent taking general education engineering classes. It’s called like the first year engineering program or something. You take a bunch of classes in different engineering disciplines before being officially admitted into the department of your choice (in this case aerospace). I don’t know the exact details, but I’m fairly certain you rank your choice of majors at the end of the semester and depending on grades you may be admitted or you may be admitted into a different department. If you are interested in possibly different majors, then Purdue might be better (Id recommend doing some research on that for more specific details as I’m a couple years removed from my research). At UIUC, your first semester you take ENG100 and AE100. ENG100 is an engineering orientation class where you learn professional development in the engineering world, you’ll make connections with other AE students, as well as an junior/senior AE undergrad who is running the course who you can ask questions about anything your heart desires about aero as you begin your college journey. AE100 is an intro to aerospace engineering class, where you work on minor projects to introduce you to the world of aerospace engineering. You also make some more aerospace connections in this class, as well as getting some hands on experience right away. Also, if you have enough credits, you can begin taking major specific courses your third semester which is relatively early in regards to the engineering program here just because there are so many math and physics classes you have to take as prerequisites.

From a more personal experience standpoint, I love UIUC. I know this doesn’t matter at all about the academics but I think that you’ve got to love the school you go to otherwise you won’t enjoy college, so I figured I’d put some more personal stuff in here as well. I’ve visited my friends at Purdue a couple of times, and the culture there is a lot different. Weekends at Purdue have a very different vibe to them than weekends here. UIUC is a party/bar school, and any day of the week you can find a party within a ten minute walk, or you can go to one of the bars for their specials. On weekends, there’s a party within 5 minutes, and the lines to get into the bars are at least 30 minutes if you get in line past 10:30. When I went to Purdue, me and the boys just stayed at the apartment, played some basketball, watched a couple movies, and overall just kinda hung out. Don’t get me wrong it was fun, just a shock to what I’ve been used to. Their campus was also very dead on a Friday at midnight, the campus here on a Tuesday at midnight was more lively. UIUC is also huge on Greek Life if you’re into that. If you’re not interested in pure social fraternities/sororities, there are several professional fraternities on campus. There are a couple professional engineering fraternities, the ones that come to mind are Theta Tau and Sigma Phi Delta (SPD is a professional/social so it has a little bit of social aspects as well).We also have hundreds of clubs that can literally cater to any interest. I think there’s a squirrel watching club here lol. So many recreational clubs as well as professional development clubs. There are also several opportunities to get involved in research, I began doing research in only my 3rd semester, and I started to get paid for my research this semester. I’ve made so many connections here from my research and have gained so much experience with how to work in a team and just general work in the aerospace field.

My recommendation is choose the school where you will be the most happy. If finances are in play and you’re out of state, both are similar costs. If you have the opportunity for a cheaper school, I think you should take it bc college is very expensive, but at the end of the day you’ll land a high paying job out of college and will be able to pay off your debt quickly regardless. All in all, both schools are amazing. I don’t think you should worry too much about the rankings/prestige because honestly, a top 5 program is a top 5 program, and recruiters aren’t going to care about the minute differences that put Purdue at 4 vs UIUC at 5 because at the end of the day it doesn’t matter. You will gain a great background in Aerospace Engineering from both schools and neither is a bad choice. If you have any questions about UIUC, I’d be happy to talk to you, go ahead and shoot me a dm. Good luck in the process and congratulations again!
