Dependency proof for Further Leave to Remain under Family private Life (5 Years route)

Hi everyone,
My mother is extending her Leave to Remain visa in the UK as a mother of a British citizen. And I am extending my Leave as her dependent . We're both going to apply using the FLR( FP) form. Here is the link to the form should anyone is interested: https://www.gov.uk/government/uploads/s ... -04-17.pdf

30 months ago, I was under 18 so it was easy for my mother to proof my dependency on her.

Now, I turned 20 and attending Univeristy who grants me a full scholarship which cover tuition fee, college fees and living cost during term time. This means I no longer share the same address as her during my term time.

Under section 9, question 9.4, how can my mother prove my dependency on her. I really appreciate any advice.
Failure to prove my dependency would means my like is messed up, my degree would be interrupted and so on.
