Does he think you should do Dark Arts, Arithmancy and Ancient Runes, then? Those ones looked like the most useful ones to me. But, like Marvolo said, Care of Magical Creatures might be fun.

It sounds like Mr Rosier doesn't think much of Divination though, so maybe don't bother with that? It sounds a bit soft anyway, all that fortune telling and stuff.

You're really lucky having someone like Mr Rosier to advise you. I wrote to my dad to ask him, but he's not written back yet. I think they're really busy at St Mungo's at the moment because of that Black's Poison.
