Number of years of English instruction

On Wellesley’s Common App I have to answer this since I’m an international applicant (SK citizen currently studying in Canada). I’m not sure how to answer this, since I studied in Canada for 6 years including this current year, but I also completed one year of school in Australia 10 years ago. Is my total number of years of English schooling 6 or 7 years in this case? Does it have to be consecutive to count?

Don’t overthink this. You have 7 years of English schooling. If they wanted consecutive years they would have said so.
