I did my core science too. Kinda nervous Which exam board do you have, I'm AQA. I don't want to resit though.
I'm in Y10 my school hasn't said anything about if we got to results day on 25/08 so i don't even know if my school allows retakes but i think it is possible if i am still in Y10
Did you only have to do one exam? I had to do 3, for each science Love you AQA... Yay I'm yr 10 too and it's probably possible to retake with one year left.
If you did a resit would you be able to revise for your other science exams? Usually schools don't allow resits for that reason, if not at school you could always do it (resit) privately.
