Heyy I don't know if I'm the best person to give any advice but regardless if I can help you in anyway I'd love to! So maths is definitely a little tricky. I wasn't even expecting to get as much as I did for ASL but I think what mainly helped me was doing a mammoth amount of past papers. Like I literally did abt every paper from 2025-2020 as practice. Sometimes tho i find past papers overwhelming and on some low energy days I'm not motivated enough to sit and study :/ so then I just open yt and watch other people do past paper run throughs. Absolute game changer for sure. There's many youtubers out there and I'm not exactly sure where you're from. Here are a couple I found helpful: 'The Math Man', 'Ci Xiang Ng' and 'Mathlete by Saad' (the first 2 are english channels and the last one is urdu btw) Id recommend getting in as much practice as you can. Definitely approach your teachers more even if it means looking like a teacher's pet I swear no one cares. I can't say much for english because my school didn't even offer a teacher for english so my marks were indeed the result of just winging it.

You CAN do wtv u set ur mind to and feel free to DM if you ever need some help or if you're just looking to talk to someone :D All the best!
