One question--Does anyone know if the comprehensive Official CLEP Study Guide offers the same practice questions as the individual course study guides? It is $25 and it says it contains sample questions for all 35 tests but I wonder if it offers fewer of these sample questions...[/quote]

For the most part yes, they contain the same questions, however I have also found that the downloaded guides from the official site may contain several new/different questions too. Either way you look at it, the book is a mere $25.00 whereas each download of individual exams ar $10.00 EACH.

GOOD LUCK!!!
