hey aggie
When I took the US Histories, I used both the REA guide and InstantCert, which were helpful.
However, don't spend as much time on answering the question
what as much as answering the question
why. I memorized a bunch of events, what so-and-so did, when that one social group was formed, but that was all. I didn't know
why all that happened. Why did that person start that movement? (haha, I'm sorry I can't provide specific names and events - it's been a while) Why did the second World War begin? (I do remember that event, hehe)
Does that make sense? It goes a little deeper than simple facts. You probably already know that, but just giving you a heads up.
With US History II specifically, there are SO many social groups and causes, it's ridiculous. I didn't know near enough about all that. Have a general knowledge of most social groups, their names (and thus abbreviations), and purposes.
I got a 44 when I took it
and I am therefore confident that you can pass it with flying colors. Most importantly: use your practice exams as much as possible. Take them and study the answers & explanations. You need at least 60% on a practice test to be sure you can pass the real thing. When I take it again, that's what I'll be focusing on.
I sincerely hope that at least one thing I've said helps you in your studying for this test! Let us know the outcome.
