Workload & Time Management -- 3+ AP Classes?

<p>OK... so I'm going to take 3 AP Classes for my Junior year (APUSH, AP English, AP Bio), including another AP during the summer (AP Econ)</p>

<p>So for APUSH, people keep saying that it's considered the hardest class because of massive memorization and a boring teacher.
The same goes for Bio, well except the teacher was only around for a year or so, so I don't know what to expect from him. People who took the class told me that it's close to impossible to pass the course, considering that half the people dropped the class and the 80% remaining are failing.
For AP English, I know I will manage the work that is thrown at me, so I don't feel much concern for that course.</p>

<p>For AP Econ, I'm expected to take a years worth of material in 6 weeks, so I'm pretty much panicking.</p>

<p>The rest of the classes that I'm taking are Psychology, French 3-4, and Trig.</p>

<p>For anyone who took these courses, what do you propose that I do, in terms of managing my time and handling the workload?</p>
