If you need a 6, you need to tell your school that you need to do higher and explain the reason why. Its the only way to get it now. Or you can redo it next year but it might mean you have to do an extra year. Its not impossible but you need to speak to your teachers.
Agree with this. Also, no promises, but failing getting Higher a few sixth forms do offer free GCSE retakes even to people who passed w a 4/5 in English and Maths. Then again, taking a year out instead and retaking maths (instead of doing A Levels / BTEC alongside GCSEs) might be the better option if the workload sounds too heavy.
i did contacted my teacher and he said he will raise case to let me do higher only if i get grade 5 in my mock, ik i can get it but mocks are keep delaying due to covid which is waisting a lot of time
Not a maths buff but if I can do anything to help notes-wise let me know.
