Okay! So, I am a sophomore in high school. I am taking AP biology in school but, I want to self study for AP Psychology, AP Macro, and AP Micro, and hope to get a 5 on all of those. I have been wondering if I should get textbooks for those subjects? Or if I should only use review books. If there are any free online links, please send me those as well, it would be very helpful. And also, please only reply if you took these AP tests recently because I don’t know if the tests changed in a while. Thank you so much!
