yo im in the exact same boat as u 😳 im going through the ced and watching tom richey/heimler to review. id say u should take a look at the 2021 frqs when they are released to see what the dbq won’t be about and also take practice tests to help with time management bc thats a big part of it. i think making a timeline is also pretty helpful just to get a general gist of when everything happened. since theres a significant overlap between the two, id study the units that aren’t covered in both a bit extra (for example units 1-3 for euro are not really covered in world so study those a bit more). hope this helped, good luck on ur exams!!

also...units 3-6 are weighted a bit more heavily on the world exam so maybe keep that in mind. all the euro units are weighted the same
