How bad??? HELP!

<p>I just wanted to know... how bad are these grades? D: Will top 10/top 20 universities reject me automatically upon seeing them, even if I am able to justify why they're so bad?</p>

<p>Science 10 Advanced -- 92
Math 11 Advanced -- 80 (I came from a school that didn't teach much math to a school that's all math all the time... so the teacher said he will bump it up, but still... & also I'm in grade 10 taking this course because I skipped a math grade)
English 10 Advanced -- 91
French 10 Advanced -- 93
Music 10 -- 88
Geography 9 -- 94 (I took History 10 last year because math screwed up my schedule... just reversed the 2 credits)
Introductory Physics/Programming course -- 90 (seriously the toughest course I've ever taken... the teacher is notorious for being really challenging & strict; the class avg. is probably in the 60s, so will that count for anything?)</p>

<p>Last year's marks were MUCH better & next year I can guarantee they will be better. The transition to a new school kind of screwed me over, & there was some personal stuff I had to deal with as well. My avg. last year was 95. Next year it will probably be in that area again. </p>

<p>Also, do the universities look at your school profile? My school is easily the toughest in the city, & I think it sends at least one person to HYPSM every year. So they would know that, right? </p>

<p>Do you think my grade 10 marks could completely destroy my chances? D:</p>

<p>ALSO, how do American schools calculate your high school GPA? Is it something like 90% = A, 80% = B, etc? Do they count grade nine?</p>

<p>Those grades aren’t that bad. Your rank matters more, but if you do better next year you should be fine.</p>
