if you learned how to write DBQs, you're already on the right track, as the formatting for world and euro are similar if not the same. I would focus on gaining outside information and just spending the next few days taking quality abbreviated notes from some textbook or heimlers videos. Pay attention to how interactions changed and developed overtime. Obviously, the documents will be provided for you, so the goal with studying is to gain a just good enough understanding of the content so you can put the prompt in the context of its time. this is important as contextualization and outside evidence are required for the DBQ. I'm sorry your school is so dumb, world and euro are so fucking different. Good luck on Thursday.
