Chances of getting into Mcgill

<p>I've been going to an american school since 3rd grade, but as I am Canadian, my parents are encouraging me to go to mcgill to save money. I'm at the end of my junior year, and would be applying after second semester next year. I was wondering whether I should be confident about getting into mcgill faculty of arts or faculty of science. Thanks.
Current GPA: 4.00 (W4.64)
when I apply: (probably 3.95 or 3.91)
SAT (taken once; should i retake?): 690CR, 680M, 670W
Subject tests: taking spanish and math 2 next month aiming for 700 spanish and over 750 math
class rank: top 10%
honors, ap, ib classes: all honors possible freshman and sophomore year, AP NSL sophomore year (got a 5), Full IB student and plan to do well on IB Psych SL and a 6 on Spanish SL
as for my predicted score, I dont have an idea yet, but id say over a 37/46 for sure
as for Ecs, I have a lot, but I won't include them because Mcgill does not pay much attention to them</p>

<p>*also plan on taking Bio subject test in march next year because apparently mcgill asks to receive scores only before April 25, after you apply. </p>

<p>The better between IB and GPA/SAT will be used.</p>

<p>McGill Arts: Safety
McGill life science: Does that 37 include a 6-7 in math HL/SL and a 6-7 in any two of chemistry, biology or physics HL/SL? If not, aim for 700+ on each of Math L2 and biology
McGill physical science: Does that 37 include a 6-7 in any one of math, chemistry, biology or physics HL/SL? If not, aim for 700+ on each of Math L2 and biology</p>
