Averaging A+ in software Development 3/4 (weak cohort) and 1/2 IT, Averaging A In general, English, politics and averaging 70% in my other 3/4 (strong cohort)
Next year i'm doing informatics, Algorithmics, Global politics, and English language but i'm not sure about my other 1 or 2 subjects. I wasn't bad at maths per se but i (regrettably) didn't put in much if any effort because hipster teenager who hates maths.
Yeah with 5 other subjects it might be a bit much but i could probably just only do four subjects and would effectivly be doing 3 (informatics is the biggest bludge in the history of vce). anyway the other thing i'm worried about is would a university be likey to allow me to transfer after i did that unit or is there a set number of placements for 2016 graduates that they have?
Anyway thank you for your help. 
oh dude, you cant get into science at melbourne even with methods because you need one of physics/bio/chem/spesh on top of methods
from what youve said, id pick up physics next year at 3/4 (its the easiest of the 4 to pick up without 1/2), and then just do introduction to mathematics in your first sem of a B.A at melb then aim to transfer.
also make sure you get a high atar and average in uni to maximise ur chances of success in transferring.
worst case you do arts with a double major in politics economics with a diploma in informatics
now that ive said it, i think thats your best course of action ^^
id just do introduction to mathematics at uni in first semester, that way you can give it alot more attention than you would give methods 3/4 in year 12
please keep in mind though, courses that have certain pre-requisites have those pre-reqs for a reason. computer science/software gets VERY VERY mathsy. alot of the subjects have first year uni math as a pre-requisite as well. if you arent good at math or dont like it, or arent prepared to take it seriously, then computing areas will be very difficult. even in economics at higher levels, you really need methods knowledge and then it goes past that. if you wanna major in economics in arts you will still have to do some uni math as well on top of introduction to mathematics
good luck
