I have each book but I want more. I have a little over 2 months to study so I should be good. U.S. history is my strongest subject. I took one of the practice tests and only missed 2 questions about pre-columbian era. Any good resources would be amazing.
I guess use Google? I’m using books but as you said, you have them. For World History, use Barrons. They have a lot of topics that are covered.
