David Palfreeman has participated as a judge in F1 in Schools events at a State, National and International level and provides his feedback on the process of judging students portfolios; the areas students should focus on when developing their portfolios and where they sometimes go wrong. Input from a judges' perspective on the judging process which participants in F1 in Schools, SUBS in Schools, 4x4 in Schools and Space in schools should find invaluable.
