I do think that if you can get out of the class, you should. If you cannot…
adam norris’s youtube channel has great review videos. Try to find example short answers and essays, and go through them while looking at rubrics. I got the princeton review book for the course, but some of the information regarding how the test is graded and the format of the exam itself was just wrong. the actual review and content is good. Especially when answering multiple choice questions, go with your gut and remember that if 1 part of an answer is the slightest bit wrong, the entire thing is wrong. I also think that when writing the essays, connecting everything to the thesis is very important. imagine that you are weaving a beautiful web of history with plenty of examples.
Good luck!
