Question about schulich school of business?!?

[lisa]

I live in Canada and I want to apply to York University for their schulich school of business program. I'm going to take The Victory Lap in high school to retake english for some personal because I could not achieve the mark i wanted to get the first time for some personal reasons. Therefore, I was curious if me re-taking a course, especially something like english, will affect on how my application will be viewed. Will they deny it just cause ? please explain me more of how the application process works and etc. Thank you
