im gonna actually go insane because of hl history

hey so i already made a post asking for help regarding hl history but because no one answered im making a second one. Look history used to be one of my favorite subjects esp in dp1 when i was getting 7s but now im one week away from mocks then my finals in 2 months and i actually have NOT figured out how to study for this fuckass subject

previously i would just revise my notes and wing it since im a pretty smart person so i relied on my critical thinking skills to score 7s on paper 1 and 6s in paper 2 but now even after i FUCK myself memorizing my 70 page notes i cant get higher than a 3. A 3???????? im actually dying over here idk i never learned how to actually study for this course and i scared im gonna be cooked for finals so please i need help can people give advice on how to effectively study as WELL as do good in the papers like i really want a 7 overall i was predicted a 5 but my school has a policy of underpredicted all classes by one so im technically predicted a 6 and my teacher even told me that i deserve a 6 but whatever THATS NOT THE POINT i had a whole breakdown to my teacher because i just got a 4 on my previous test like a week before mocks and she kept telling me you're too stressed and im not worried about you doing bad in the finals but like shes under the pretense that i know what im doing and IM REALLY NOT so

sorry if this is widely incoherent if u guys cant tell im genuinely going through it

so far, as i gathered from other online forums, everyone is saying to split notes into syllabus requirements then just grind past papers but idk this seems so intimidating cuz its just SO MUCH CONTENT and my only problem isn't history i still need to catch up on math and chemistry so im fr cooked does anyone have any advice pls pls pls
