You might find Seitzman's lecture notes to be helpful.
When I took 3450, we used the blue and orange book (probably the one Jagoda is pulling questions from). It's actually selected sections from two separate books compiled specifically for that course. I thought the second half about gas dynamics was pretty good, so you might want to look for that as well.
If it's any consolation, the gas dynamics portion of the class isn't hard so much as incredibly tedious. Just a couple monster equations and the rest is just ratios. Figure out which ratios you need and how to manipulate them and you'll be good to go.
Aside from that, study and pray to the curve. Good luck!
well you can read course curriculums, hell you can take all of MIT's aerospace engineering courses online for free im sure. they have lectures and exams available.
high level textbooks...after the calculus/physics ones?
important math is just calculus, differential equations, linear algebra. arguably algebra and trigonometry are the most used and needed to master.
no knowledge of any engineering is required for engineering students coming in.
btw astronomy is basically useless unless you want to do planetary science...orbital mechanics is a separate field
