ATS1340 - English for Academic Purposes (
http://www.monash.edu.au/pubs/handbooks/units/ATS1340.html) Haven't done it but apparently pretty breezy if you're a native english speaker. The imrpoved skills will help you throughout your entire degree as well. Have not attempted this one myself.
SCI1020 - Some people might be prohibited from doing it depending on their units (?) but it's basic statistics. It assumes you did no highschool mathematics. A lot of it is just using excel (or so i'm told), i'm currently taking it right now and its been easy so far (albeit very boring).
BIO1011/1022 - Exam is all multiple choice. Should be decently easy enough for anyone who did VCE bio, can still be content heavy though, unless you like biology or need to do it, i wouldnt consider it a breezy unit.
ASP1022 - (Listed in yours too). Very interesting, decently easy. It's similar to some UoM style breadth subjects in that it covers heaps of things and has many guest lecturers (astrobiology, computer AI, evolution, etc). A great subject. Will be much easier if you've taken some kind of biology or astro prior to this unit (not hard in semester 2).
ATS1310: Extreme earth! Natural hazards and human vulnerability - All about geography (so how humans and the enviroment interact + more). You look at all kinds of natural disasters - flood, fire, earthquake, pandemics, etc. It's very interesting (who doesn't like volcanoes!?!) and the labs are usually either easy or fun and engaging (we played the boardgame Pandemic in one of them!).
Distance philosophy - You get to nominate the mark you want (up to D). IF you don't get it, you're entitled to try again after you receive your corrected assignment. I really love philosophy, so, i find it a bit hard to gage how others might view it. Most have one lecture a week, so, 12 hours represents all the lectures for the subject! If you don't like philosophy or your writing isn't the best, i can see how this might not be as breezy (still pretty breezy).
Ultimately, any subject you love will be way more cruisey than one you don't want to be there for as well. I took chem having no desire for chem and there's no surprise i did bad.
