2021 OCR A2 Chemistry unofficial markscheme (additonal materials)Watch this thread
hey, does anyone have the 2019 papers for chemistry OCR B? (I know they're locked on the website, but some schools gave the locked papers to students to revise) please I'm not looking to cheat or anything, our school is making up their papers. I just need every extra practice I can get, please help!!
I can send scanned on some socials, tsr takes a while.
