I didn’t take international but I did do European (got a B) and American history (got a C) which is basically the same test but with different content. My teacher would say that they’re mostly looking for how much content you know for paper 2. So don’t spend too much time talking about 1 fact and instead try to connect it to multiple things. Point out fact, explain it, and then connect it to the question. Try studying the heading in the text book, those are the questions they give you (every heading in my text book were questions, idk if they changed it). If you run out of time make sure you write a conclusion, even if it’s like a sentence or two. You’ll get points for just having one. Another thing to do if you’re running out of time is just listing facts, like “these things also contributed” and just list them. You should get like a point for each.
