How long would it take for a Canadian student to study for SATII?

<p>I'm a Canadian junior and planning to take SAT II fairly soon.
Probably I'll take Bio, MathII, and World History... but I'm not sure how long it will take to study all of them.
I'm in Bio so I know all the basic stuffs but I think I need to study just a few things that I didn't learn here in Canada.
And Math... I'm not super good but not bad at all... so I'm going to study anyways.
The problem is World History. We don't learn history except for WWI and WWII in high school. But I LOVE history so I will enjoy studying it. But would it be really hard if I didn't take history course? And how long would it take to study it?</p>

<p>And overall, how long would it take to study all 3 subjects when i'm aiming for 800?</p>

<p>I’m also a Canadian (gr 11). I did my Math II, Chem + French on Saturday after a month of self-study. </p>

<p>Are you doing any IB/AP courses in those subjects? Any grade 12 courses? I’m doing my IB exams on Math + French this month (IB math in 2 days!) and did semester of HL Chem in IB1 which really helped in everything in regards to studying and self-learning the stuff I didn’t learn here. </p>

<p>Are you taking it in June? Or October? Go to the library and check out some books and try reading some of the stuff. See if you can realistically prepare in the time allocated.</p>
