AP Art History self-study suggestion?

<p>I know that there are undoubtedly other threads on this, but can someone who has had experience with a self-study for APAH tell me what I need to do to ensure a 5?
What books/materials do I need to get?
How much time and effort do I need to put into this?
How hard is it really?</p>

<p>Thank you so much!</p>

<p>Also, I will be doing the following next year in school: AP US History, AP Calc AB, AP Physics B, and AP Lang.</p>
