Although this will not happen, it might be good if the following were offered as VCE 3/4 subjects:
Perhaps General Senior Science, which enables students to learn all three sciences in one subject (and perhaps a bit of psychology, or at least the physiology of the brain and nervous system) but in less depth than the individual subjects of science - obviously it would involve vastly different course content from the biology, chem and physics subject (although It'd be a pain to find someone who'd teach it).
and Foundation English available at units 3/4
students who are not strong in English should be able to attain a study score in this subject and thus should be able to get an ENTER score.
