OUAc application question

I didn’t know how to answer this and I was hoping someone would clear this up to me
“indicate the total number of years in an English language school system outside of Canada (excluding kindergarten)”
I study in the uae and we start studying english from kindergarten but its not the main language, I study in a public arabic school which means that I study math, chemistry, physics… etc in arabic. so do I answer it with 12 years or none? because technically the system isn’t engish.

thank you

It’s asking about studying at an English institution where the language of instruction is English not whether you studied English at an Arabic school. To prove English proficiency you will need to submit your TOEFL score.
