I've completed the AP Biology course on Khan Academy, but I found the wording of the 2013 AP Biology practice questions to be a bit confusing. I know that I understand the concepts and definitions of all the terms, but I'm struggling with the phrasing of the questions. Would it be helpful for me to use textbooks, practice problem books, and the free Edx course to better prepare for the AP Biology course? Moreover, I really appreciate how you took t8me out of your schedule to look at my post, and I believe that your response would mean even more to me. Thank you.
