I said Herculaneum had a grid pattern... pretty sure it does, and it divides the city into the typical Roman insulae. But whatever, exam was moderate over all and now the HSC is done!
pretty sure you can't predict pompeii and herculaneum because it's only been going for two years.... so really they can ask anything barring religion/forum. oh but it will probably be conservation for the third question, cause ethical issues are pretty non-existent and they've asked...
