Does the “The Official Study Guide for All SAT Subject Tests” contain different practice material than the official study guides for individual topics? For example, if I am studying for the Bio M Subject Test, will the 2 practice tests in the Official Study Guide for Biology be different from the practice tests in “The Official Study Guide for All SAT Subject Tests”?
They are the same for Math 2 and US History.
I think they should be the same for Biology as well.
The two tests offered in the official study guide for Biology are different than the book with all tests. It was published last year and offers two NEW tests. I have both books so I know the answer for fact. That is also true for the chemistry guide which is also published last year and offers two new tests.
That’s good to know.
CB Math 2 and US History have four tests each, and they include the tests in the All book.
