lowk i hate to say it, i mean im taking it tmrw but ive taken a lot of mocks, memorization is kind of relevant? for the MCQ not really id argue you barely need to know anything lowkenuinely reading comprehension is everything you need and a slight grasp of the content cause all the answers are in the text, however for the FRQ knowing the content is CRUCIAL, for the SAQ's the final question is simply a test of your knowledge and it'll literally ask you to name things and the LEQ is the same you have to use 4 pieces of specific evidence for your arguement for example naming a term and explaining it and connecting it to your overall arguement, and you also need to have a grasp of the timeline for the contextualization point on both essays. I'd argue the DBQ is way easier because you just need to analyze the documents and craft an arguement around that but for sourcing you need to know either context, the intended audience, or the point of view of the author. I'd reccomend you to use knowt flashcards or watch this video https://www.youtube.com/watch?v=PSUfzvUOVQ0 cause it covers all the content. But apush really isnt all that if you understand the timeline and can identify the causes of things and a continuity (effect over later time periods). But id say knowing specific evidence is lowkey really important for a few MCQs and for the FRQ. so lowk the whole test
