APUSH and AP Chem

<p>I'm a sophomore taking APUSH and AP Chem this year. My question is how I should go about studying for these exams? Considering the fact that AP Chem will be more difficult that APUSH, should I study each day 2 hours chem and 1 hour APUSH? Or should I break up the days and do 2 hours of each until the test day?</p>
