Advice for AP Classes

I am going to be a Sophomore in high school next school year and it’s my first time taking AP classes. I am planning to take AP Human Geography, AP Psychology, and AP Capstone - Seminar. I need some help for the following:

  • Which AP prep book should I buy for AP HuG and AP Psych (is there one for AP Sem)? I want to choose between The Princeton Review and Barron's.
  • Are there other websites/resources that you recommend to help me prepare for these 3 AP classes? -Any general advice and tips?

Thank you so much for the help!
