what i was told that we don't need to know lewis theory 😭 we only should know Lavoisier, humphrey-davis, arrhenius and bronsted-lowry
but maybe don't take my advice, my teacher's been wrong many times
nah i don't think so, honestly just making notes in yr 10 can help u refresh ur memory when u revisit them in yr 11/12, but i would say tut isnt worth it at this time
if its quotes and doesn't take long to make flashcards outta them, write them on a piece of paper and constantly get someone to test u. the pressure of someone watching u revise is good
if u need prelim practice, maybe look for yr 11 content in trial papers eg for math and chem. i did that and it helped significantly tbh
ik this isn't related to chem or physics, but doing this especially helped in English
some of it also depends on the quality of ur teachers at school. if u find that ur teachers rarely give you feedback and you dont benefit from the school lessons, def consider a tutor. otherwise, a good teacher and a good textbook is often all u need to pull urself up
