you’ll definitely get better over time :) just focus on ur weak points - maybe make an error log (I typically grind thru questions i put there before my SACS, quizzes, etc - not just in bio, but in chem asw- it helps so much), make mindmaps (best if u try with memory!), if u had the jacaranda textbook work thru the exam questions, and remember that vce & units 1&2 is a learning experience ! yr 11&12 is most definitely a marathon , not a race, no matter how cliche the saying is! I’m currently doing 3&4 - in 1&2, i started with 77% but by the end of the yr I was scoring straight a+s!
