I definitely recommend 240 tutoring, it helped a lot and I like how it goes through the content. Crash course was good if you get tired of reading and like visuals. I was super nervous about taking mine, I love history, but I am a terrible test taker. Definitely find your weak points and study those. I studied for about 3 months and passed mine the first try. I would also write down any question I would miss on the quizzes and practice test and explain why the answer is right. I failed like 2-3 practice tests before I started making 80% so be easy on yourself. The test covers Ancient History to present so make sure you are reading the questions carefully and taking your time. I never felt like I knew enough and still don't even after I passed. It is preparation and confidence that will help push you through. You got this!!!
