Can i be an internal and private candidate for alevels and gcses?

I'm planning on doing gcse physics and then alevel physics privately or just doing alevel phyiscs privately. My main issue is that I'm doing gcses as an internal candidate already. I'm probably going to do AQA physics but if other exam boards don't have this issue then I'll do a different exam board. But basically on AQA's website about private candidates that "Note: You cannot be entered as both an internal and private candidate at the same school/college, and in the same exam series."
I'm fine with being a private candidate at a different college than the one I'm an internal candidate at, but i need to do physics in the same exam series as my other exams otherwise I'd have to finish my other gcses and alevels and then do alevel physics and I'm not gonna spend two whole years privately studying for 1 subject.
It also says "and" not "or" so I'm not sure if this means i cannot be a private and internal candidate while doing both these things (same exam centre/college and same exam series) OR if it means i cannot be registered as a private and internal candidate while being in the same exam centre, and also i cannot be a private and internal candidate if I'm doing exams in the same exam series OR if it means i can't register as a private and internal candidate for the same exam during the same exam series/season.
So my question is can i be a private candidate for one subject and its exams (alevel physics) while also being an internal candidate during the same exam series but for other alevel subjects with their own different exams?
