Taking difficult courses earlier?

<p>So I'm from Canada in my sophomore year and I took AP Calculus (my only AP this year) and I'm getting a 92% (not sure what that is on the 4-point scale). So I'm wondering if taking a hard course now and getting a decent mark is more beneficial than getting a better mark in my junior or senior year? Will taking Calculus early look impressive to universities even if I didn't get an amazing mark?</p>

<p>Thanks</p>

<p>I mean, jesus, a 92%… that’s really good… I’m a senior, and the majority of the class is getting C’s and B’s. So as a sophomore? Getting an A- in AP Calc? That’s pretty damn good. Just keep up your smartness, and you’ll be good :P</p>
