Feeling okay about biology (finally), I was getting C's earlier this week and atm getting 130UMS+ (got 140 twice), what I did was go through THIS THREAD and find all the answers for possible six markers people and gave and made my own revision cards by writing them down. I then last night identified topics I wasn't great at (water movement in plants etc) and spent 30 mins on each topic just reading notes and reading stuff online, recording myself saying notes and listening to them. After 30 mins, even if I wasn't 100% there I moved on to the next one. Good luck everyone!
