for me, it really depends on who you are. some kids overseas (in highly competitive countries) study >8 final-year subjects in a year and still get fabulous marks, so that shows you that it is more than possible to do 6 VCE subjects in yr 12. i think that with great time mgmt and the 'right' mindset you can seriously do it!
i may or may not be doing 6 subjects in '08 (incl. one UMEP), as it says in my sig, but one would be a repeat if i did. on that note i need some advice...i won't reveal my methods cas SS, but my situation is this: i studied hard and found methods easy this year, after SACs and exam 1 should've gotten very high SS, but exam technique let me down in exam 2 which brought down my SS. i pretty much need 99+ ENTER, and this would be a very easy repeat for me...but is it worth my time? any thoughts...
