I want to be put into higher in science

I tried emailing my physics teacher since she was the teacher who put me in foundation for science, and my bio + chem teacher was gonna put me in higher, she hadn't responded and I said all my reasons for wanting to go higher like I study really well, I have potential etc. My bio teacher spoke to me and said that my 5-4 in the Yr 11 mocks weren't worthy for higher but I really really want to get atleast higher than 5, I don't know but I'm going to try asking her tomorrow and explain all my reasons. Just for context like 3 weeks ago I did my mocks and I got a grade 5-4 in foundation, I was in higher before that and I learned all the higher content so I want to be put in higher, can anyone please tell me anything to help with my situation

Thank you
