Y12 predicted grades

HI
i got a C in my biology mock, need to get a B in the next exam so my teacher could give me a B
I wanted to ask whats the deadline for schools writing ur predicted on UCAS and can you change your predicted grades between now and September

Yes, the UCAS deadline is October. Schools do not base your predicted grade solely of mock results, they also base it off classwork, topic tests, other mocks, homework, behaviour, and any super-curriculars you are doing related to the subject.

Are you sure the deadline is october because my college have a deadline in 2 weeks of september....

Deadline to submit UCAS is around 14th October (6th ish for medics, Oxbridge). Schools may have earlier internal deadlines to make sure you have the application ready

In which case you will have up till your schools deadline to submit your application and up till that time to have a chance to change your predicted grades

so for law the deadline is 31st jan, because of my schools internal sep deadline do i have to apply in september....also how can i ask my teachers to bump my predicted grades, i have a medical reason for my exam performance from sep to jan...for english we hsve coursework which my teacher will look at in early sep and for my other subject we have mocks in sep but for biology if i dont get a B or higher in the next exam my teacher will write me a C....i need AAB for law
