@AzureBlue, swarley and pi: Get real!!! OK fine, it is possible for me to 50 one or more of physics, chem and spesh. Hate to disappoiint you, but to 50 englang would be extremely difficult for me, but I guess it's possible (maybe a 71-72/75 in the exam would do it?) and to 50 german is definitely out of my scope, seriously. Mark my words, I'd be struggling to get a 40.
@luken: Spesh - I wouldn't separate spesh into "unit 3" and "unit 4" because it's a maths subject with no two clear "units." I would say go through as much of the textbook as you can, and use VCEnotes or others for help.
Chem - just get the whole thing over and done with! It does take a while for the concepts to be processed by your brain.
OK, I guess my real aims are straight 50s, but putting that on sig would sound cocky, but here are my most likely scores:
Englang - 45 (47)
Spesh - 48 (51) --> just two careless mistakes will do that
Chem - 49 (49.4) --> will lose a mark somewhere
Physics - 43 (45) --> if fuzzylogic can't get over 43...
German - 39 (47) --> scaling saves me here...
UniChem - 5.5? --> i'd better hope so
Agg: 208.4
Hold on - that gets me 99.95...surely this can't be right
