VAPD: not that important.
Well I've noticed that the VAPD diary isn't really important except for school assessment tasks where development is important, but other than that... the markers marking your HSC will not even look at it unless they suspect that the work is not fully done by yourself, if they need to check what your concept of your artwork is or if you're artwork has been selected to be printed in the Art Express, they will check you diary for some information about your work to put in the Art Express. If you do Textiles, you'll know that a supporting document is to be handed in with you major work... this is very different to art, although you have to submit your diary or a process of how you constructed you artwork, in textiles, the portfolio is worth 50% while the major work is also worth 50% so alot more work is put into the portfolio, this is not the case with art, it is not as important as your major work.. so u don't have to stress to much
