Ah, this is where our differing educational systems might cause some issues. Since some countries will have more artisan subjects (such as Food Tech, Design and Technology or Textiles) in addition to your traditional languages, maths and sciences. Then you have vocational subjects, like Engineering, Health Care or Business.
Bit late for me to make such a suggestion, since we're two polls in already. Perhaps before changing polls, you should take a screenshot and archive the results. We could try redoing polls every so often to see how things have changed.
