Has anyone used Barrons AP Book to prepare for this? If so, does anyone else think that the sample investigative tasks are FAR harder than those on the actual test
I think everything in the barrons stats review book is more difficult.
The general rule for quantitative subjects is that Barron’s books are more difficult by intention. You may or may not subscribe to their line of thinking, but it’s based on the principle that if you “overprepare” for the test, you’ll be well-equipped to handle the questions that will be on the (comparatively easy) test.
