What happens if i need a 5 in maths for biology, but only reach a grade 4?

i am a 2021 GCSE students and my exams are about to finish. I have always struggled hugely with maths, i have had a tutor for a few months beforehand too: it didn't help much. Though my paper 3 exam seemed easy to me , but i am not confident that i have reached a grade 5.
i need a grade 5 for Biology A - Level, will they still let me take it if i do not reach it?

It very much depends on your school. I originally wanted to do further maths a level which required grade 8 but I was 1 mark off and got a grade 7. I moved to a different school for 6th form but they said if I really wanted to do the further maths a level they would allow me. The same thing happened to my younger sibling who also moved to a new school for 6th form. I think it you’re staying at your current school they may be more likely to allow you to do the a level even if you don’t get the grade because they know you and your capabilities, however it really does depend on your school.

Your maths needs to be good for a level science subjects, if not you're really going to struggle. What are your other a level options that you are consideri

It's up to your school to decide if they will let you but they don't make these requirements up for fun - you may well struggle with the Maths in Biology if you aren't at (at least) grade 5 standard.

my original plan was biology, psychology and socioogy, my back up plan would be english lit, psychology and sociology , or replace sociology with criminology , these are my grades rn...
english lit/lang : 6
maths: 4, maybe a 5 if i reached it
religious studies: 7
history : 8
biology : 6
chemistry: 6
physics: 4
catering , and health and social care ( BTEC ) : distinctions
though i was told they may take my other grades into consideration if i dont get my maths to grade 5, i rly wanted to take a science but they all require a 5, it may be that they consider my other grades and think i am capable, but idk...

Hey girl I’m in the same situation did they let you study it?

im literally in the exact same situation as you rn, did you school end up letting you study it?
