i need someones opinion

im starting ib year 1 one this year. for some reason my school moved ESS to group 6 but im taking theatre in that block. my school said ess online is an option but im not sure whats better. like idk if i can rely on myself and make sure my notes that i do will suffice for ess as its like a completely new thing. but im doing bio and it seems really hard and theres a lot to memorise bc i didnt so well in my igcses so im not sure if doing ess online is worth the risk.
