Umm a lot of textbooks these days have exam style Q's within them so you could do those 

 Also, as you've mentioned the vcaa exams are great (and don't just stop at 2010, go all the way back to 2002's VCAA HHD exam! The Unit 3 part of the study design has remained largely the same since 2002 (with exceptions, such as not focusing on preventative model of health as much these days) so don't look it over!) 

 Also, if you want Q's for a particular key knowledge dot point of the study design (that you cant find Qs for in vcaa exams or your textbook), post that dot point in the HHD Q's thread and I or any of the other past hhd students can try and think up a Q for it 

 ALSO, there is a sample exam on the vcaa site, and although it doesn't have answers, its Q's might be good for practice
