<p>if one takes world history AP, how difficult is it to self study the european history AP test. How much more would you have to learn?</p>
<p>I self-studied for the World History AP test last year, and I'm taking an independent study AP Euro class this year. I have literally done nothing all year, yet I recently took a practice test and scored in the 5 range. So I'd say it's very possible to do well on the Euro test if you thoroughly know the World History curriculum. That said, while there is some overlap between the two tests, the Euro test goes into significantly more depth, so doing well would require a decent amount of studying. Very doable though.</p>
