Just a young confused child.

<p>Alright, so I'm 15 years old, and ever since I can remember I've been stressing about my education. </p>

<p>My first question, is which grades actually matter?
I've heard a multitude of stories, from grades 9-12 being a big deal. I've also heard that the only grades universities will look at is grades 11-12. </p>

<p>I've also heard that you show your six best classes? This worries me, because I've slacked some classes that I disliked, and I don't want that to effect my odds of getting into a university. Right now I'm standing at a 90 in Grade 11 academic English, but in my computer engineering course I ended up with a 74. Will this effect my odds of admission into a university, regardless of the education? For example, law, considering it has nothing to do with the engineering of computers. Basically, I'm just curious on how universities will judge my grades/how they look at them. </p>

<p>Secondly, I've heard that AP classes help A LOT. I'd definitely be up for AP classes, except my school has none. How much does this damage my chance of admittance into universities? </p>

<p>I've also been checking up on athletic scholarships. But I'm not really sure which sport would be the best, in terms of chances of earning a scholarship. Considering I'm half a semester ahead in school, I've debated taking a semester off school in order to train myself for whichever sport I decide. It would be like a normal school day, except I'd just dedicate it to that sport. Would this be a good way to up my chances of getting a scholarship?
The sports I've been considering are rugby, football (soccer), and track. </p>

<p>In all, what makes or breaks admittance into a decent university.
Thanks!
Hope this was understandable.</p>

<p>Oh, this is definitely in the wrong section. How do I remove the post?</p>
