I guess this is important to some, if even a minority.
In reference to seng unsw students (first year students),
As you know, in semester 2, if you pick the mathematics subject as an elective, it clashes every way you try due to the core subjects of software. This is easily fixed by going to the mathematics faculty and asking them to move a set of the lectures (e.g. calculus or algebra) onto another day that has them running.
Basically you are mix and matching the two lecture options you can pick at the my.unsw, into a situable one. (my.unsw doesn't let you mix and match, that's why you ask the maths faculty to override it and enrol you into it).
I guess if you want, and if you can tell the mathematics faculty without confusing them, you may be able to do it over the phone.
This fixes the clash with choosing mathematics as an elective in semester 2.
