can i jump 2-3 grades in 2 months

is it possible if i can skip a few grades.....
currently i have mocks in march and if i dont get above a grade 7 then i will move down to double science and foundation in math and german
i would be extremely grateful for advice....im literally so sad i cant even explain
here are my current grades
3,4,4,5,5,5,5,6,6,6,
i must get 8's and 9's in my gcses which is in 96 days!!!

It isn’t possible I managed to jump from a 4 to a 8 in 4 of my subjects in 4 weeks.
Just be very consistent with your revision.
