Dear Xavier I think I can help you.
Explain to your mother all the pros of going to the college you wan to go to first then explain to your mother all the cons of the university or college she wants you to go to. Also explain why it would be of good benefit for you to go to the college/University that you want to attend.
Best wishes,Naomi
