Hi i'm in year 10 and my teacher just dropped a bombshell on our class today that we have our gcse french speaking exam mock on thursday and he's only just told us today meaning i have very little time to prepare (only 3 days) I'm not too bad at french but i'm really worried since this mock has come out of nowhere, i hate that my teacher has only told us now and the fact that my teacher could ask me literally any question is stressing me out (the whole having to prepare for everything). We haven't even gone through the roleplay and the photo card section of the speaking exam thoroughly in class yet he expects us to follow through with the speaking exam on thursday. What's the most effective way i can revise with the little time i have and how can i get high marks?
