Want to change GCSE option at the end of Year 9

Hi! I want to change from Business Studies to French. They're in the same options block, and French lessons occur at the same time as Business. My form teachers are both French teachers, and and I got some of the best grades in my French class in Year 8. My French teacher at the time actually said to me that she was a bit bummed that I didn't choose French. Also, the teacher that said it teaches the Foundation class I would move to.
Do I bother with trying?? I am a bit apprehensive of my Head of Year and I have a feeling they don't like me I do well though and I have good attendance, have good grades, and am a student leader (like that'll help, but context is necessary folks)! I would study hard for French. The only thing is that they've said no to people that literally begged to change.
Also, for context purposes, I said to them back in December that I would be interested in switching to French.

Hm it depends on whether your teachers are willing to look into it or not - sometimes you will be allowed to change it a few months into the course, but I'm not sure how that will play out as it's pretty late (assuming you already started your gcse courses by now - correct me if I'm wrong).
It's good you're willing to work hard for it, but really consider if you would be able to catch up or make the most out of your lessons. And if your teachers don't let you switch, then don't worry too much, as you can still self-study french if you're passionate about it!
Hope that helps and good luck!
