BOS Trial 2014 Extension 1 Solutions & Marking Criteria (1 Viewer)

[Carrotsticks]

Hi all,

Apologies for the delay, but we now finally have solutions, marking criteria and markers comments!

Please let either myself or Trebla know if you find any misprints.

We hope that these will be of some use to you either in your future HSC (for students not doing the HSC in 2014) or for your exam on Tuesday (for the 2014'ers).

Good luck to everybody for your HSC examinations, and I'll see you all (again) on Tuesday for my HSC solutions =)

Carrot.
