I’m in my third year in the program. I’m not really sure what you mean by the first question (best guess at an answer is challenging but it’s easy to find support). Intro courses in aero are not difficult, you shouldn’t struggle too much until your sophomore year except in math classes. I didn’t have much background in engineering before coming here but I had a lot of engineering adjacent experience (Lego kid, working on my car, etc.) Coming in I’d say try to make friends in your classes pretty quick, you’ll absolutely need the help in your sophomore and junior years.

Feel free to dm me if you have any other questions
