Please tell me a way on how to study for AP classes. Let's just say are there any sites besides Khan Academy that teach you and you take tests etc to measure your understanding? Lately, I have been very confused on how to study for the chapters. I mean reading the entire chapter takes a lot of time from the textbook and plus the next day you forget some percent of the information. Also, by the time class test is there you have to again spend hours and hours. Can someone tell me to be more productive? I mean I go home and I am only able to focus on a single subject. Please guys help me and also don't judge me by my screen name. I work hard but somehow when the test day is there I am fatigued and I don't even feel like doing anything. I have AP Chemistry, AP Physics 2 and AP Calculus. Can You please how to manage time between these? Is there a site where I can learn better? How is Princeton or Kaplan? Or any other ? Please guys its the beginning of the year and I want to get everything together.
