I took this as an elective - This is a really enjoyable course - Also the easiest course I've taken. 20% of the marks are literally free, most people I know who actually gave a damn in this subject got either a D or a HD. Playconomics is actually surprisingly enjoyable as a game, it's not a chore to play, just do it periodically to avoid massive all nighters near the end of semester to finish. The content is very interesting (though if you did HSC Economics, probably a bit repetitive), and although there is math involved, it's not hard. If you did alright in Year 10 math, this will be fine for you.
Sarah was good as a lecturer, but in the end I found it easier to self teach from the textbook (not difficult, the textbook is fabulous).
I highly recommend this as a Gen Ed. Not too difficult conceptually, so it won't take heaps of time away from more difficult courses from your stream, but very interesting nonetheless!
