if you go brampton sixth form please help me!!!

im a year 11, my parents really want me to go to brampton sixth form and will literally murdr me if i dont get in bc theyve spent years on my tuition, im currently on 5s, mostly 6s ,7s but i moved down for spanish i think .. my next set of november mocks are what they're going to use for my predicted grades. im trying to achieve 7/8s for the next ones so they can predict me a grade higher and 9s for gcses. i do higher for everything except spanish now because my spanish teacher forgot to put up my writing test along with my listening and reading in the year 10 summer mocks meaning i couldve gotten a higher grade, before failing it because of that i got a 7 in the test before but dropped down because of the mistake on the system. ive been doing higher for spanish all this time and the highest i can get in it is a 5 now. say for example i get 8s and 9s in everything but a 4 or a 5 in spanish, is there still a chance they'll accept me? i feel like i need to tell my spanish teacher about the mistake but i'm scared that she'll think i'm not capable of doing higher even though ive done it this whole time..

thank you so much!!! i'll try my best to get all 8s and 9s, i wanna do psychology, sociology and politics
