Cegep choice

What cegep between vanier regular health and brebeuf regular health should I choose to get into med. I’ve heard that since the standard deviation is bigger at vanier ur r score is affected by that is that true. What cegep will get me a higher r score with the same grades. And does med school consider your cegep or only your r score, like is 35 r score at either the same to them? Thank you for any help.
