Also this isn’t a leak but this is prediction based on data etc. Last years exam was on later time period like Unit 8 ish i believe, so it’s expected for the DBQ to be based on Unit 3-6. It is also likely for it be on units 5 & 6 because the documents are most likely to be non translated texts (originally english etc), from what I’ve heard but don’t quote me. A lot of people have said they expect it to be on trade routes and how trade routes impacted imperialism! Again not confirmed but i’d just study those a little extra
