UBC Vancouver B.A. chances?

<p>Hi, I'm a senior in an American High School. I want to know my chances of getting into UBC for Fall 2014.
I have a 3.62 GPA unweighted/ 4.28 GPA weighted (does weighted become a factor?)
High School Rank: 57/292 unweighted (19%), 38/292 weighted (13%)
SAT I: 1980 superscore (670 reading, 690 math, 610 writing)
SAT II: 650 Literature, 730 Math I, 670 Math II
I have a lot of musical extracurricular activities
-Lead Pianist in Jazz Band (we went on tour in Europe to international jazz festivals twice)
-Lead percussionist Symphonic/Marching Band, Symphonic Orchestra
-Piano Teacher
-Volunteer pianist at church mass
And other ones such as:
-NHS
-AP scholars
-Board Member of SGA Executive
I also have an internship at one of the World Trade Centers in my area.
I do other things, but those are my main EC's</p>

<p>Do I have a good chance of getting in UBC Vancouver for the Arts? If not, should I retake any tests? Thank you!</p>

<p>UBC Arts: Low match</p>

<p>Could I know why?</p>
