Please Help Predicted Grades

Hi I am currently in year 11 and recently I flopped my combined science biology test ( I got 28%), however in my year 10 mocks I got 88 and predicted 88, will this affect my year 11 prediction or will it only be my mocks that I have in January that will and is it still possible for me to get predicted 99 if I get 99 in my mock. Any replies will be appreciated I have been so stressed

As long as your grades are consistently good and it was just a singular test that was bad then it shouldn't really affect your predicted grades especially since you take combined science too.
However, I recommend you to ask your science teachers as they are the ones who usually set the predicted grades.

Hi thanks for replying and yes I asked and she replied that I will have more tests to come to "paint the picture", but how are predicted grades normally made I thought it was just your mocks
