<p>I was just reading through my princeton review AP Euro book and it says that Verdi wrote Carmen. Uh...he most certainly did not. Bizet did. Verdi wrote alot of famous operas, why mix him up with Bizet?</p>
<p>That's kinda common knowledge too (atleast it would be to an academic). I feel like no longer trusting the princeton review.</p>
<p>yea, in my Princeton Review Calc Book, they don't teach you how to do Lagrange error bounds correctly.</p>
<p>why, what do they say?</p>
<p>We have never found a test prep book that DIDN'T have errors. BC Calc, Gov't, Stat, CS AB, WH, etc. The books just haven't been vetted the way CB materials are. We run into lots of poorly worded Qs in the test prep books too. The real tests seem easy after wading through some of these books -- and the variable quality is a good reason to have a textbook or other sources to study from as well. If you're self-studying from a test prep book and haven't seen the material before, you may have no idea what's accurate and what's garbage.</p>
<p>In the PR Calc book on one of the practice AB tests they have a question about finding inflection points and they do not find it properly and they do not verify the inflection point even though they tell you in the chapter to always verify.</p>
<p>in a pr prac test for calc ab, the book says the area of a quarter circle with radius 2 has an area of pi/4...when it should be pi</p>
<p>I've found a few.</p>
