As an examiner of many years' experience for a major awarding body, I'm doing an AMA for you to put your questions regarding the setting, administration and marking of your upcoming examinations. I principally mark Biology, but have also marked Chemistry. I'm happy to answer questions about these sciences in particular, or more general non-specific subject questions. Candidates often have misconceptions surrounding the marking and moderation of their papers, and maybe I can dispel a couple of them via this thread. For instance - if you write outside the box, it will be marked!
I will not comment on the adequacy or otherwise of individual answers to particular examination questions, so please don't post questions which ask this.
Ask away.
NB: the views and advice I give here are based on my own personal experience and observation. They are not the views of a particular awarding body, nor are they officially endorsed by one. Should you have specific, substantive queries about your individual examination entry, you must contact your school/college tutor or Examinations Officer about it.
