Flying high - crashing low...

Just got back the feedback and mark from my first assignment - am now very sad! I thought I had 'unpacked' the question and answered what was asked but obviously not quite enough. Even reading the comments I am unsure how I would have changed it - very frustrating. In the 'critical' discussion of the role of the TL and the ALIA/ASLA standards it seems I was too negatively critical - it is always hard to be objectively critical about something. Most times if asked to be critical I know I tend to approach it as a bit more of an argumentative type piece. The first assignment back from a new lecturer/university always gives you a bit more of an idea on what sort of things are expected I suppose. Am now somewhat dejected about assignment 2 though...
