biology u3/4 study advice
so ik that the year has basically ended but like ive tried everything and my grades are going like a roller coaster (up and then downa nd then back up).
my sacs results:
U3 AOS 1(CRSPR)=80%
U3 AOS 2(PHOTOSYNTHESIS)=70%
U4 AOS 1 (IMMUNITY)= 73%
U4 AOS 2 (EVOLUTION)= havent done
U4 AOS 3(enzymes + key science skills)=90%
so my first sac this year was U4 AOS 3- and i studied for like 2 weeks and got that good score.
then we did U2 AOS 2 and i got a 70%, which is like a 20% and i didnt do what i did for the first sac bc im also doing methods 3/4 and had that sac (im in yr 11) . then for the crispr sac i studied rlly had- but they gave a dogshit article so thats why i lowkey did a bit bad, but i knew all the content.
for immunity i studied hard but i only rlly understood the content like 3 days before the sac and my errors was just relating it back to the article and to like read the fucking question.
so now for my last sac i wanna do well but idk how to study for it since its like massive and i cant memorise shit. sounds bad and is bad but like i can only understand content. i want a good way to not break my mind but also know everything.
pls give me a way to rember or to learn all the content without dying!
p.s. when i study i spen like 3 hours doing it and im like not production- like other than being distracted, im genually slow asf when studying. how can i be productive when studying large content and not dying!!
