How much homework for these classes? Realistically?

<p>Hey guys,
I'm a Canadian student and my school only offers APs in our senior year. I've decided to take:</p>

<p>AP Chem
AP Physics II
AP Calc AB
AP Microecon</p>

<p>In addition to those classes, I'll also be taking:</p>

<p>Biology 12
French Enriched 12
English 12
Senior Wind Ensemble</p>

<p>Oh and also Graduation Transitions/Planning 12</p>

<p>In Canada we normally take 8 classes a year and because there are many classes that are mandatory from grade 8 to grade 12, it has left me with an extremely crammed schedule for grade 12. I'm also interested in Psychology and World History but I think that it'll be too much. And it's weird because classes like History and Psych are ones I'm very interested in, but I get lower marks in those classes. As for the sciences, I'm not as passionate about them (I do find it interesting still) but I tend to excel in those classes. </p>

<p>Any help would be greatly appreciated! Thanks ^^</p>
