Good idea LOL thanks
Also what sub topics would you have for animals and food? Do you get to choose your sub topics? Like what if the examiners ask you a question outside of your sub topics?
I reckon for animals, you can say their eating habits, their features and maybe a legend or story about the animal while for food, you can say the history, why is it famous and where is it commonly eaten and things like that

If they ask you something outside your sub topics and you can't answer it, I would say:对不起,我没有研究到这个,但是 (link to something else). But I'm not really sure

I think it's mentioned once on the exam reports

If you would like, I'm willing to help even more over PM

Just send me one and I don't bite

( I just don't want to post too much on the forum and let other not AN people see...)
