For my Aero/Sci 1st year, I did
Semester 1
MTH1030, ASP1010, PHS1080 (or PHS1011 if you did VCE Physics), ENG1060.
Semester 2
MTH2010, ASP1022, PHS1022, MAE1042.
If you have an interest in Astronomy and had been reading up ALOT on astronomy prior to this, I'd recommend that you do ASP2011 in semester 1. However if you're new to astronomy and have just a basic understanding of the celestial coordinate system, orbital mechanics, name/properties of planets etc. etc.. I'll recommend ASP1010 as it covers more introductory stuff.
ASP1022 is a massive waste of time in my opinion as its more like an uni covering the culture of astronomy instead of actual astronomy. There's people who enjoys it though so idk but all of the astronomy subjects are a buldge subject compared to the engineering/physics/maths units.
