Need help?

Hey guys I am currently taking 4 ap classes this year AP literature and composition, AP Biology, AP U.S. History and maybe AP Calculus AB but I wasnt sure if I should also self-study AP European History? I mean I love history especially european history but I’m not sure self-studying will do it because last time I self-studied for an ap I didn’t do well. Any suggestions or advice for me?</p>
